If the NullPointerException is observed with out the object closed exception it is caused by a DB2 problem see the following link http://www-01.ibm.com/support/docview.wss?uid=swg1IZ27010 This APAR will make sure that this method is not returned to the application in the case were the connection is already closed. Note: This APAR is created for DSRA9110E: Connection is closed not for NullPointerException.

Problem conclusion
The actual problem is with DB2 code and the fix is available at http://www-01.ibm.com/support/docview.wss?uid=swg1IZ27010. As explained in this link, customers are recommended to upgrade their DB2 version. This IBM WebSphere Application Server APAR, PK86552, handles the exception gracefully and provides temporary relief to the customers who cannot upgrade the DB2 version immediately. The fix for this APAR is currently targeted for inclusion in fix packs 6.0.2.37, 6.1.0.27 and 7.0.0.7.
