NullPointerException when a null value is set in the properties map passed to Entity.createEntityManagerFactory
---------------------------------------------------------------------------------------------------------------

                 Key: OPENJPA-1746
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1746
             Project: OpenJPA
          Issue Type: Bug
          Components: jpa
    Affects Versions: 1.2.2
         Environment: N/A
            Reporter: Robert Flaherty
            Priority: Minor


If a property is set with a null value in the Entity.createEntityManagerFactory, a NullPointerException
is thrown due to PersistenceUnitInfoImpl's use of Properties for the _props field (which extends
Hashtable which doesn't allow nulls).  Although not specifically laid out by the API, it accepts
Map, which is incompatible with Properties/Hashtable in this instance.  HashMap would be the
preffered type here.

Currently this was working with EclipseLink, as I set some properties to null to override
defaults set in the persistence.xml file based on some dynamic criteria.
