> I've only seen this as an issue when using Oracle's XMLType and using openjpa.jdbc.SchemaFactory=native
to build mapping information from the database. There may be other ways this problem can be
exposed.
> Recent versions of the JDBC driver for Oracle return 2007 as the DATA_TYPE for XMLType
column (observed on 11.2.0.1.0). Earlier versions (10.2.0.3.0) returned java.sql.Types.OTHER.
What's odd is that I don't see 2007 as a defined constant  for java.sql.Types - as a result
OpenJPA throws an exception citing an unknown column type. It's not clear to me whether this
is a bug in the JDBC driver or something we need to adapt to, or whether 2007 was just a holding
place for Types.SQLXML (which is set to 2009). 
> As a workaround we can treat 2007 as Types.OTHER for Oracle (at least for OpenJPA 1.2.x).
