WebSphere throws an exception when attempting to close a connection in RDBMUserLayoutStore under WebSphere 6.1 . This exception is thrown when an attempt is made to close a connection with an uncommitted transaction.

This exception was introduced in WebSphere 6.1. In org.jasig.portal.layout.simple.RDBMUserLayoutStore.getUserLayout
~line 1563 sets up a transaction that is not *always* committed. Although this code hasn't changed from 2.5.1 to 2.5.3, WebSphere 6.1 vs WebSphere 6.0 refuses to close the connection with an uncommitted transaction. The stack trace is included for context:
