Hi Mike, thanks for the information. I'll open a JIRA and investigate.....

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.. I

Hi, I notice that occasionally when I build various versions of OpenJPA
(e.g., trunk, branches\1.2.x, tags\1.2.0) the enhance.all.entities ant step
will getting many numerous ZipException's (see below). So I was just
wondering if anyone knew what might be causing this ?? And why the build
doesn't stop when it does happen ?? I guess I don't yet know enough about
the "enhancer" to fully appreciate/understand what it does, but I would have
expected the build to fail and stop immediately..... Thanks....
