I've been working ok with my OpenJPA 1.2.2 app for a while. I'm using
build-time enhancement, and "openjpa.RuntimeUnenhancedClasses" is set to
"unsupported". I had my "openjpa.Log" property set with the "basic"
strategy, not using log4j or commons-logging. It was working fine. I
then decided since I was using log4j with other components, I wanted
openjpa to use that also. I changed the value to "log4j", then added a
"logger" element in my log4j.xml for openjpa. I started up the server,
and got the exception that follows this.
I don't see why it suddenly thinks I need to use a -javaagent. I'd
prefer not to do this. I certainly don't need "load-time class
transformation", if that's what the build-time enhancer does.
