Problem conclusion
Modified the code to get the poolmanager from ConnectionFactoryDetails before using the poolmanager object and also to check if poolmanager object is null to avoid NullPointerException. APAR PM35291 is currently targeted for inclusion in Service Level (Fix Pack) 7.0.0.19 of WebSphere Application Server V7.0. Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
