From 1896876d66b0ee06c50a75501faf99dffba4aa81 Mon Sep 17 00:00:00 2001 From: Jonathan Schneider Date: Mon, 1 Jun 2026 12:13:03 -0400 Subject: [PATCH 1/5] Groovy + Java: route ShallowClass.build through the JavaTypeFactory MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Several parser code paths used JavaType.ShallowClass.build(fqn) directly — for dotted-name expressions where each segment becomes a J.FieldAccess (rewrite-java-{8,11,17,21,25} + rewrite-groovy), and for dynamic parameter / catch-block / NoClassDefFoundError fallbacks in rewrite-groovy. ShallowClass.build allocates a fresh JavaType.Class every call — bypassing the parser's configured JavaTypeFactory entirely. With a type-table-backed factory, this means a single parser session emits multiple non-canonical instances for the same FQN: the symptom that surfaced this was two distinct java.lang.Object proxies showing up in one build.gradle parse, and later a JavaType.ShallowClass for org.gradle.plugins.ide.eclipse.model.Classpath colliding with the factory-produced JavaType.Class for the same FQN. Each affected TypeMapping (ReloadableJava{8,11,17,21,25}TypeMapping, GroovyTypeMapping) now exposes classFor(fqn) which routes through typeFactory.computeClass — the factory's cache dedupes per signature, and a type-table-backed factory returns the full body it carries (the helper is NOT necessarily a "shallow" class, the prior name was misleading). All parser-side ShallowClass.build call sites switch over. The Groovy-side NoClassDefFoundError fallback in GroovyTypeMapping.type also goes through classFor — same identity-stability reasoning, since e.getMessage() is the FQN of the missing class and the factory will synthesize a canonical stub for it. --- .../groovy/GroovyParserVisitor.java | 14 ++++++------- .../openrewrite/groovy/GroovyTypeMapping.java | 16 +++++++++++++- .../ReloadableJava11ParserVisitor.java | 2 +- .../isolated/ReloadableJava11TypeMapping.java | 16 ++++++++++++++ .../ReloadableJava17ParserVisitor.java | 2 +- .../isolated/ReloadableJava17TypeMapping.java | 16 ++++++++++++++ .../ReloadableJava21ParserVisitor.java | 2 +- .../isolated/ReloadableJava21TypeMapping.java | 16 ++++++++++++++ .../ReloadableJava25ParserVisitor.java | 2 +- .../isolated/ReloadableJava25TypeMapping.java | 16 ++++++++++++++ .../java/ReloadableJava8ParserVisitor.java | 2 +- .../java/ReloadableJava8TypeMapping.java | 16 ++++++++++++++ .../org/openrewrite/java/tree/TypeTree.java | 21 +++++++++++++++++-- 13 files changed, 126 insertions(+), 15 deletions(-) diff --git a/rewrite-groovy/src/main/java/org/openrewrite/groovy/GroovyParserVisitor.java b/rewrite-groovy/src/main/java/org/openrewrite/groovy/GroovyParserVisitor.java index feb5f630f0b..2bfc13c63e9 100644 --- a/rewrite-groovy/src/main/java/org/openrewrite/groovy/GroovyParserVisitor.java +++ b/rewrite-groovy/src/main/java/org/openrewrite/groovy/GroovyParserVisitor.java @@ -1057,9 +1057,9 @@ class B { class B { TypeTree paramType; if (param.isDynamicTyped()) { if (sourceStartsWith("java.lang.Object")) { - paramType = new J.Identifier(randomId(), whitespace(), Markers.EMPTY, emptyList(), skip(name()), JavaType.ShallowClass.build("java.lang.Object"), null); + paramType = new J.Identifier(randomId(), whitespace(), Markers.EMPTY, emptyList(), skip(name()), typeMapping.classFor("java.lang.Object"), null); } else { - paramType = new J.Identifier(randomId(), EMPTY, Markers.EMPTY, emptyList(), "", JavaType.ShallowClass.build("java.lang.Object"), null); + paramType = new J.Identifier(randomId(), EMPTY, Markers.EMPTY, emptyList(), "", typeMapping.classFor("java.lang.Object"), null); } } else { paramType = visitTypeTree(param.getType()); @@ -1530,7 +1530,7 @@ public void visitClassExpression(ClassExpression clazz) { skip(classSuffix); } } - queue.add(TypeTree.build(name) + queue.add(TypeTree.build(name, null, typeMapping::classFor) .withType(typeMapping.type(type)) .withPrefix(prefix)); } @@ -1799,7 +1799,7 @@ public void visitCatchStatement(CatchStatement node) { !source.startsWith("Exception", cursor) && !source.startsWith("java.lang.Exception", cursor)) { paramType = new J.Identifier(randomId(), paramPrefix, Markers.EMPTY, emptyList(), "", - JavaType.ShallowClass.build(Exception.class.getName()), null); + typeMapping.classFor(Exception.class.getName()), null); } else { paramType = visitTypeTree(param.getOriginType()).withPrefix(paramPrefix); } @@ -3446,7 +3446,7 @@ private JRightPadded convertTopLevelStatement(SourceUnit unit, ASTNod Space importPrefix = sourceBefore("import"); JLeftPadded statik = importNode.isStatic() ?

That dedup'd identity but didn't fix the underlying issue: ShallowClass mapping was used in many places where the parser actually had richer information available — Symbols, ClassNodes, ImportNode chains, etc. — and was choosing a string-keyed stub instead. This commit walks each parser and replaces classFor with whichever of these is appropriate at each call site: * typeMapping.type(astNode) — when the parser holds a Symbol / FIR node / IrClass / Groovy ClassNode that the existing classType path can populate fully * reflectionTypeMapping.type(Class.forName(fqn)) — when the FQN names a real Java class we can resolve via reflection (Kotlin's kotlin.String -> java.lang.String remap, Scala's Constants.StringTag, Kotlin's synthesized String method parameter) * typeFactory.computeClass(fqn, flags, kind) { /* empty */ } — when we need a canonical identity-stable Class for an FQN that has no backing AST node (JVM file facades, JvmPackagePartSource library facades, Scala library types we don't want to recurse into) * JavaType.Unknown.getInstance() — when the thing isn't a class at all (Kotlin package directives, IrExternalPackageFragment, unresolvable JavaClassifierType classifiers, the synthetic "kotlin.Library" placeholder) After this pass, no caller of classFor remained, so the method is deleted from JavaTypeFactory and its implementations. TypeTree.build's 3-arg form (introduced in the prior commit) is likewise gone. Specific notable changes: * Groovy J.Import qualid now walks the ImportNode's outer-class chain segment-by-segment, so `import com.foo.Outer.Inner` attributes Outer and Inner to their real ClassNodes instead of routing the string through TypeTree.build. * Kotlin file facade classes (FooKt) now carry their declared top-level functions on the canonical Class. MethodMatcher patterns against Kotlin top-level functions work for the first time. * Java parser visitors lose their buildName helper, which was dead code reachable only from visitTypeParameter with a single-segment name. * KotlinTypeMappingTest test expectations updated where the new behavior is more correct: arrayOf's declaringType is {undefined} (no real class, kotlin.Library was a placeholder string), and operator expressions on Kotlin primitives uniformly surface as the JVM primitive int rather than splitting between unary (int) and binary/assignOp (kotlin.Int). --- .../marketplace/RecipeClassLoader.java | 2 +- .../org/openrewrite/gradle/GradleParser.java | 10 +- .../org/openrewrite/groovy/GroovyParser.java | 18 +- .../groovy/GroovyParserVisitor.java | 156 +++++++- .../openrewrite/groovy/GroovyTypeMapping.java | 108 +++--- .../ReloadableJava11ParserVisitor.java | 45 +-- .../isolated/ReloadableJava11TypeMapping.java | 348 +++++++++--------- .../ReloadableJava17ParserVisitor.java | 45 +-- .../isolated/ReloadableJava17TypeMapping.java | 171 ++++----- .../ReloadableJava21ParserVisitor.java | 45 +-- .../isolated/ReloadableJava21TypeMapping.java | 171 ++++----- .../ReloadableJava25ParserVisitor.java | 45 +-- .../isolated/ReloadableJava25TypeMapping.java | 173 +++++---- .../java/ReloadableJava8ParserVisitor.java | 45 +-- .../java/ReloadableJava8TypeMapping.java | 347 +++++++++-------- .../JavaTemplateParserProviderTest.java | 36 +- .../java/org/openrewrite/java/JavaParser.java | 32 +- .../java/internal/DefaultJavaTypeFactory.java | 130 ++++--- .../internal/JavaReflectionTypeMapping.java | 107 +++--- .../java/internal/JavaTypeFactory.java | 221 +++++++---- .../internal/JvmsTypeSignatureBuilder.java | 6 +- .../internal/template/JavaTemplateParser.java | 8 +- .../org/openrewrite/java/tree/TypeTree.java | 27 +- .../org/openrewrite/kotlin/KotlinParser.java | 16 +- .../openrewrite/kotlin/KotlinIrTypeMapping.kt | 79 ++-- .../openrewrite/kotlin/KotlinTypeMapping.kt | 242 ++++++------ .../kotlin/KotlinTypeMappingTest.java | 17 +- .../org/openrewrite/scala/ScalaParser.java | 16 +- .../scala/internal/ScalaTypeMapping.scala | 61 +-- 29 files changed, 1351 insertions(+), 1376 deletions(-) diff --git a/rewrite-core/src/main/java/org/openrewrite/marketplace/RecipeClassLoader.java b/rewrite-core/src/main/java/org/openrewrite/marketplace/RecipeClassLoader.java index b36b06c4fd9..5da39b193f6 100644 --- a/rewrite-core/src/main/java/org/openrewrite/marketplace/RecipeClassLoader.java +++ b/rewrite-core/src/main/java/org/openrewrite/marketplace/RecipeClassLoader.java @@ -101,7 +101,7 @@ public class RecipeClassLoader extends URLClassLoader { "org.openrewrite.java.TypeNameMatcher", "org.openrewrite.java.internal.TypesInUse", "org.openrewrite.java.TypeNameMatcher", - // Cursor-message wiring (TYPE_FACTORY_PROVIDER_KEY) passes a Provider + // Cursor-message wiring (TYPE_FACTORY_KEY) passes a JavaTypeFactory // implementation across the recipe/parent classloader boundary; the // interface must be shared so the cast in JavaTemplateParser succeeds.

    + *
  1. {@code compute*} — stub-then-initialize. The factory + * constructs a stub, registers it in the cache, then runs a + * {@link Consumer} that populates the stub via {@code unsafeSet}. + * Registering before the initializer runs is what makes recursive + * resolution during the initializer safe — reserved for types + * whose construction graph can recurse back to the same key: + *
      + *
    • {@link #computeClass} — Java's class graph is mutually + * recursive ({@code Foo extends Bar; Bar.field is Foo}).
      • + *
    • {@link #computeParameterized} — F-bounded polymorphism + * ({@code Comparable>}) and Kotlin + * parameterized self-refs.
      • + *
    • {@link #computeGenericTypeVariable} — type variable + * bounds can reference the variable itself + * ({@code >}).
      • + *
    2. + *
  2. {@code *For} — atomic build. The caller supplies a + * {@link Supplier} that returns a fully-constructed instance; the + * factory caches and returns it. No half-built object is ever + * observable through the cache. Used for variants without self-recursion + * on the same key: {@link #methodFor}, {@link #variableFor}, + * {@link #arrayFor}, {@link #intersectionFor}.
    3. + *
*

- * The construction surface is the {@code compute*} family. Each - * {@code computeXxx(signature, ..., initializer)} returns the cached instance - * if one already exists, otherwise allocates a stub, registers it in the cache - * before invoking the initializer, then runs the initializer to fill - * the stub's fields. Registering the stub up front is what makes recursive - * resolution during the initializer safe: a recursive lookup for the same - * signature finds the stub instead of looping. The initializer typically ends - * by calling {@code unsafeSet} on the stub to populate its fields. + * Parser code that needs a canonical identity-stable {@link JavaType.Class} + * for an FQN that has no Symbol/AST node (synthesized JVM facades, library + * placeholders, etc.) should call {@link #computeClass} with an empty + * initializer. There is no separate "lookup" surface — the absence of + * richer attribution is signaled at the call site by an empty initializer. + * + *

Key formats

+ * + * Two distinct keying schemes coexist; mixing them within one factory lifetime + * is a caller bug. + *
    + *
  • FQN keys — {@link #computeClass} is keyed on the + * fully-qualified name (e.g. {@code java.util.List}, + * {@code com.acme.Outer$Inner} for nested types). Universal across + * languages: every parser maps a {@link JavaType.Class} to its FQN the + * same way. The {@code fqn} value is exactly what + * {@link JavaType.FullyQualified#getFullyQualifiedName()} returns.
    • + *

Build pipelines that already attach a JavaSourceSet marker (matching the source file's classpath) attach the factory at the same time; JavaTemplate reads it via the enclosing source file's marker. Eliminates the indirection that required producers to populate a magic key on every visitor's cursor. When the marker is absent or carries no factory (free-floating Groovy/Gradle scripts, V2 LSTs, synthetic test CUs) JavaTemplate falls back to a fresh DefaultJavaTypeFactory, matching prior behavior. Also fixes the licenseTest break introduced in 96a0ec371c by giving rewrite-java-test's template package-info.java the standard Apache header and switching to the project's @NullMarked/@NonNullFields convention. --- .../marketplace/RecipeClassLoader.java | 7 ++-- .../JavaTemplateParserProviderTest.java | 23 +++++++++-- .../java/internal/template/package-info.java | 21 +++++++++- .../internal/template/JavaTemplateParser.java | 29 ++++++++------ .../java/marker/JavaSourceSet.java | 39 +++++++++++++++++++ 5 files changed, 98 insertions(+), 21 deletions(-) diff --git a/rewrite-core/src/main/java/org/openrewrite/marketplace/RecipeClassLoader.java b/rewrite-core/src/main/java/org/openrewrite/marketplace/RecipeClassLoader.java index 5da39b193f6..70be24f856b 100644 --- a/rewrite-core/src/main/java/org/openrewrite/marketplace/RecipeClassLoader.java +++ b/rewrite-core/src/main/java/org/openrewrite/marketplace/RecipeClassLoader.java @@ -101,9 +101,10 @@ public class RecipeClassLoader extends URLClassLoader { "org.openrewrite.java.TypeNameMatcher", "org.openrewrite.java.internal.TypesInUse", "org.openrewrite.java.TypeNameMatcher", - // Cursor-message wiring (TYPE_FACTORY_KEY) passes a JavaTypeFactory - // implementation across the recipe/parent classloader boundary; the - // interface must be shared so the cast in JavaTemplateParser succeeds. + // JavaSourceSet#getTypeFactory crosses the recipe/parent classloader + // boundary when JavaTemplate reads it from the enclosing source file's + // marker; the interface must be shared so the cast in JavaTemplateParser + // succeeds.

For a resolved nested-class import that chain is unreliable: `getOuterClass()` returns null even for a nested type, so the chain had a single element while the package-segment count was derived from the (multi-segment) package name. The two disagreed, which for `import java.util.Map.Entry` left the leaf `Entry` with a null type (a regression from the prior shallow type) and wrongly placed `Map$Entry`'s type on the `Map` segment. Walk the attributed leaf type's `owningClass` links instead — proper type attribution populates these from the JVM enclosing-class chain. Each class segment now carries its own resolved type, package segments carry none, and unresolvable leaves (asFullyQualified == null) fall back to no type rather than to ``. Behavior for flat, static, and star imports is unchanged. Adds a regression test asserting per-segment attribution for a nested import. Also remove the unused `org.openrewrite.java.tree.Flag` import left behind in the five ReloadableJava*TypeMapping files. --- .../groovy/GroovyParserVisitor.java | 24 +++++++++----- .../openrewrite/groovy/tree/ImportTest.java | 31 +++++++++++++++++++ .../isolated/ReloadableJava11TypeMapping.java | 1 - .../isolated/ReloadableJava17TypeMapping.java | 1 - .../isolated/ReloadableJava21TypeMapping.java | 1 - .../isolated/ReloadableJava25TypeMapping.java | 1 - .../java/ReloadableJava8TypeMapping.java | 1 - 7 files changed, 48 insertions(+), 12 deletions(-) diff --git a/rewrite-groovy/src/main/java/org/openrewrite/groovy/GroovyParserVisitor.java b/rewrite-groovy/src/main/java/org/openrewrite/groovy/GroovyParserVisitor.java index 2839bc83478..58d25c9fdae 100644 --- a/rewrite-groovy/src/main/java/org/openrewrite/groovy/GroovyParserVisitor.java +++ b/rewrite-groovy/src/main/java/org/openrewrite/groovy/GroovyParserVisitor.java @@ -4163,15 +4163,26 @@ private String name() { * identifier segments. */ private J.FieldAccess buildImportQualid(ImportNode importNode, Space prefix) { - // Build [outermost, ..., leaf] class chain.
