> If a JDBC URL is specified with an incorrect protocol or subprotocol in combination with
a JDBC Driver class when configuring a PU an NPE is thrown within the OpenJPA code when trying
to create an entity manager.  The NPE bubbles out to a not-so-useful PersistenceException
with internal StoreException containing message text "null".  
> For example:  (note the missing colon after the subprotocol)
> openjpa.ConnectionDriverName=com.ibm.db2.jcc.DB2Driver
> openjpa.ConnectionURL=jdbc:db2//my.database.com:800/MYDB  
> Results in:
