I know.  I just said that because it is somehow related...

Re: [jira] Created: (OPENJPA-96) Runtime Enhancement only processes first 
persistence unit defined in persistence.xml






Vlad,
I'm currently not specifying a persistence file on the javaagent 
parameter.
I only specify where to find the class files for kicking off the runtime
enhancement:

-javaagent:C:/eclipse.workspaces/3.2rc2/openjpa/openjpa-all/target/openjpa-
all-0.9.7-incubating-SNAPSHOT.jar

I let the runtime find my persistence.xml file in my META-INF directory.

Kevin
