I've posted this issue on StackOverflow with screenshots here:
http://stackoverflow.com/questions/9672641/strange-build-status-for-jenkins-maven-submodule
This is Jenkins 1.450 building a Maven 3.0.4 project (as a maven project, not
free form) with many submodules.
I was noticing some strange behavior that one artifact appeared to have stale
classes. When I dug down into that artifact build I noticed it appeared to
have several zombie builds running for days/weeks (see screenshot at link), yet
no executors were consumed. I didn't follow the "Jenkins hung" process, but
restarted both slaves and the master (sorry!). After restarting the main
project, which had appeared to be unstable (sadly this is normal for us), now
showed all builds as failed! This is "strange issue #1".
Digging into the logs I noticed that this particular submodule was throwing an
OutOfMemoryError while building, but Jenkins (or Maven?) was labeling it as
successful:
Exception in thread "main" java.lang.OutOfMemoryError: unable to create new
native thread

Triggering a new build of foo-main-cobertura #345
Finished: SUCCESS
and was building downstream projects despite the fact that the build failed
with an OOM error. This is "strange issue #2".
I've increased the heap as far as I can with the 32-bit JVM so I'm switching to
a 64-bit JVM trying to get a good build for QA.
Any ideas about these two issues:
1. Seemingly good/unstable builds switching to red (failed) after Jenkins
restart
2. OOM error during build interpreted as successful
