Splits a block of code into two reordered sub blocks and wraps the first block in a fake trap.

CFR

CFR decompiles the method but merges the second block into the try block with the first block resulting in behavior change.

JD-GUI

JD-GUI decompiles the method completely wrong. The result is a behavior change and unreachable code. Decompiled result of poc.jar:

import java.io.PrintStream;

public class Test
{
  public static void main(String[] paramArrayOfString)
  {
    for (;;)
    {
      System.out.println("Hello #2");
      return;
      try
      {
        System.out.println("Hello #1");
        null;
      }
      catch (FakeException localFakeException)
      {
        return;
      }
    }
  }
}
