Enhancer questions/problems

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....

Re: Enhancer questions/problems

Posted by Michael Dick <mi...@gmail.com>.
Maybe I missed the JIRA you opened, but I ran into this problem again over
the weekend.

FWIW I hit the problem with Ubuntu 8.10, 64 bit with either the IBM SDK or
Sun JDK. I didn't try openjdk.

The problem for me had nothing to do with ant, that was a complete red
herring. It turned out to be due to my own lack of *nix knowledge.

I ran ulimit which returned "unlimited" so I thought I was in good shape. It
turns out that I needed to run "ulimit -n" which returned 1024. This can be
increased by editing /etc/security/limits.conf. A newbie friendly reference
is available at [1].

Increasing the limit resolved the problem for me, YMMV.

Re: Enhancer questions/problems

Posted by Michael Dick <mi...@gmail.com>.
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
