Hi.

Might have found a "bug".

This could be replicated with a malformed persistence.xml. You have

to

create a configuration without any classes specified then the

QueryCache

will throw a null pointer exception.

104  test  INFO   [main] openjpa.Enhance - You have enabled runtime
enhancement, but have not specified the set of persistent classes.

  OpenJPA

must look for metadata for every loaded class, which might increase

class

load times significantly.
