OracleDictionary.getEmptyClob uses its classloader instead of the current classloader. 
---------------------------------------------------------------------------------------

                 Key: OPENJPA-542
                 URL: https://issues.apache.org/jira/browse/OPENJPA-542
             Project: OpenJPA
          Issue Type: Bug
          Components: jdbc
    Affects Versions: 1.0.2, 1.0.1, 1.0.0
            Reporter: Michael Dick
             Fix For: 1.0.3, 1.1.0


The OracleDictionary class calls Class.forName("oracle.sql.CLOB") and Class.forName("oracle.sql.BLOB")
to get the class objects for BLOBs and CLOBs. This approach uses the classloader which loaded
OracleDictionary, which might not have access to the Oracle JDBC classes ie if OpenJPA is
in a different OSGi bundle from the jdbc driver. 

Instead we should get the current classloader which is more likely to contain the JDBC driver
classes.
