My guess, and it's only that, is that we're hitting an issue with ant. I think it is or is related to this bug : https://issues.apache.org/bugzilla/show_bug.cgi?id=38260.
On Linux I've seen similar intermittent problems (mainly with trunk) that show the "too many open files" symptom described in the bugzilla report. I have not seen the errors if I manually update pom.xml to use ant 1.7.0 but that might just be luck. Regarding the enhancer there's information in the OpenJPA manual regarding what enhancement does [1]. Regarding the enhancement process during the build I'm not sure why the build doesn't fail after that exception. There might be a bug in the way we're using the antrun maven plugin or a bug in enhancer.xml..
