…iant Add a Java integration variant anchored on a real Spring Boot example app (example-apps/java-spring-boot): the posthog-server client is exposed as a singleton @bean configured from the environment, flushed and closed on shutdown via destroyMethod="close". A controller identifies users, captures events, evaluates feature flags with evaluateFlags, and reports errors as an explicit event (the Java server SDK has no automatic exception capture, documented honestly rather than faked). Ships a full Spring Boot example rather than docs-only so the wizard has a concrete shape to match for the most common Java backend framework. Adds a java-server commandments block, keyed java-server (not java) so these backend rules never fold into the Android skill, which carries the java tag; the variant is tagged [java, java-server].

changed the title
evaluateFlags() makes a network call. Wrap it in try/catch so a slow or down PostHog can't 500 the /dashboard page (fall back to the flag off), matching the Elixir example's behavior. Add a note that a real app should cache/bound the call rather than fetch per render. Also document that distinctId must come from an authenticated principal, not an unverified request parameter, so the copied pattern doesn't invite person-property spoofing.

Adds a full example-based Java integration variant (not docs-only), anchored on a real, compiling Spring Boot app at
example-apps/java-spring-boot— the most common Java backend framework, called out specifically in review.What's here:
example-apps/java-spring-boot/—posthog-serverclient as a singleton@Beanconfigured from the environment, flushed + closed on shutdown viadestroyMethod="close". A controller identifies users, captures events, evaluates feature flags withevaluateFlags, and reports errors as an explicit event (the Java server SDK has no automatic exception capture — documented, not faked).gradle compileJavaclean.config.yaml: newjavafull variant, tagged[java, java-server].commandments.yaml:java-serverblock — keyedjava-server(notjava) so backend rules never fold into the Android skill, which carries thejavatag.Ships as a pair with the wizard detection PR PostHog/wizard#948.
