Date Wed, 08 Jun 2011 20:11:58 GMT
Duplicate meta data warning logged due to parsing the same location twice
-------------------------------------------------------------------------

                 Key: OPENJPA-2010
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2010
             Project: OpenJPA
          Issue Type: Bug
          Components: kernel
    Affects Versions: 2.1.0, 2.0.1
            Reporter: Michael Dick
            Assignee: Michael Dick
             Fix For: 2.0.2, 2.1.1, 2.2.0


I've only seen this when entities are defined in an XML mapping file, and then only in some
difficult to replicate classloader environments.

The same XML mapping file may be parsed more than one time, resulting in a misleading warning
message about duplicate metadata. The metadata is in fact identical, and does not indicate
a problem. 

To detect this condition we can store the source file and line number where the meta data
was defined, and only issue the warning if the metadata is defined in a different location.
