Description

This bug seems to have been introduced while cleaning up some openjpa-maven-plugin compiler warnings in r1091279 / OPENJPA-1934.

When you try to invoke the MappingTool with mvn openjpa:sql you will get the following failure:

[ERROR] Failed to execute goal org.apache.openjpa:openjpa-maven-plugin:2.2.0-SNAPSHOT:sql (mappingtool) on project enhance: Execution mappingtool of goal org.apache.openjpa:openjpa-maven-plugin:2.2.0-SNAPSHOT:sql failed: Type "class org.apache.openjpa.tools.maven.testentity.TestEntity$SampleEnum" loaded by java.net.URLClassLoader@49c1e1e7 does not have persistence metadata. -> [Help 1]
