Subject [jira] Commented: (OPENJPA-932) Runtime enhancer doesn't work propery if there is a trailing persistence.xml file on the classpath.

Michael Dick commented on OPENJPA-932:
--------------------------------------

Hi Rick,

The current patch will *always* log to StdErr. I think we'd be better off saving the fact
that there was a name collision and logging it after we've parsed the configuration.

I'm also not sure we need a new logging level for this issue. Wouldn't one of the other levels,
ie Runtime have sufficed?

> I have an application where I am using runtime class enhancement via the javaagent and
I set openjpa.RuntimeUnenhancedClasses=unsupported. My application works fine when running
on 1.1.0 but when I moved to 1.2.0 (and 2.0.0) I started getting errors because my classes
aren't being enhanced. 
> After debugging I determined that I had a jar on the end of my classpath that had a META-INF/persistence.xml
file in it. The extra persistence.xml file has no PUs defined, and should have been ignored.
When I removed that jar from my classpath things starting working again. It also works if
I put my META-INF/persistence.xml file on the end of my classpath.
