When we build wildfly master on some of our CI cluster machines (and Toms laptop) we are getting GC overhead limit exceeded errors building the Full Feature Pack. This started happening about 6 weeks or so ago. We have fixed it in our config by passing "-XX:+UseConcMarkSweepGC to maven via MAVEN_OPTS but ideally it needs setting in the wildfly build script. The maven error is:
[ERROR] GC overhead limit exceeded -> [Help 1]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
