I can reproduce consistently without Gradle. Command below:

"C:\Program Files\Java\jdk-13.0.2+8-openj9\bin\javac.exe" -cp lombok.jar lombok-mre\src\main\java\Test.java

It looks like a general protection fault in the OpenJ9 library j9jit29.dll. I'm little a fuzzy on this topic but if remember right that usually means that j9jit29.dll tried to access memory space it wasn't allowed to access. Windows raised a fault and the JVM couldn't recover.

This works ok when I compile with JDK 13.0.2 and without OpenJ9. I don't think there is anything the Lombok project can do to fix this. It looks like a bug in OpenJ9. I'm linking the OpenJ9 issue that is investigating this. As a workaround, I suspect you can compile without OpenJ9 and then use OpenJ9 for runtime.

The issue is due to the different field layout algorithms in Hotspot vs OpenJ9 and can be fixed by making the "Fake" class have the same fields as AccessibleObject - see @fengxue-IS's PR #2437 - so that it works regardless of changes to the field layout algorithms.

Can someone confirm the fix in the edge release?
