Just saw a StackOverflowError in Javac.

Interesting fact is that it happens on Jenkins CI but not at my system, with the same JDK version on Linux.

[INFO] Compiling 40 source files to /mnt/hudson_workspace/workspace/Windup-daily/windup/rules-java-ee/target/classes


The system is out of resources.
Consult the following stack trace for details.

Turns out to be caused by different RHEL Javac defaults.

MAVEN_OPTS=-Xss1024k fixed it.

I specifically use the "Invoke top-level Maven goal" in Jenkins CI, so "-Xss1024k" goes to the "JVM Options" field.
