> Closing a resultset after retriving BLOB or CLOB data > 32K, does not release locks
properly.   Network Server uses getClob, getBlob to retrieve the data even if the application
uses getCharacteStream, etc, so holds locks to the end of the transaction.
> To reproduce run attached repro
> java LargeDataLocks derbynetclient
> To see the difference with embedded
> java LargeDataLocks derby
