Description Michal Huniewicz CLA 2011-07-23 13:24:14 EDT 
Build Identifier: 

When null persistence unit name is provided to the Persistence.createEntityManagerFactory(...) I get an exception, even though a single persistence.xml file with a single persistence unit exists. This should be handled according to JPA.

Versions:
org.eclipse.persistence.eclipselink 2.3.0
org.eclipse.persistence.javax.persistence 2.0.0

Comment 1 Tom Ware CLA 2011-08-02 15:35:10 EDT 
Closing.  I cannot find a section in the specification that indicates that this should be supported.  Please quote a spec-reference and reopen if you can find it.
Comment 2 Tom Ware CLA 2011-08-02 15:36:33 EDT 
On second thought, changing to enhancement.  Please feel free to change the severity back to the original value if you can find a spec reference indicating this should be supported.
