Problem description:
===================
When I am serializing the java.sql.DataTruncation class in JDK 1.5 and 
deserializing it in JDK 6.0, the value of DataTruncation.getSQLState()
is not the same.

Please see minimized test to reproduce the failure.

This incompatible serialization change in the java.sql.DataTruncation class
prevents  correct serialization/deserialization of DataTruncation 
between different versions of J2SE (for example, 1.5.0 <-> 6.0).
