Subject Enhancer questions/problems
Date Thu, 05 Feb 2009 22:40:05 GMT
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....
