Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V7.0, V8.0, and V8.5 * **************************************************************** * PROBLEM DESCRIPTION: ORB FVD callbacks to a WebSphere * * Application Server for z/OS client * * address space fail with a * * java.lang.NullPointerException. * **************************************************************** * RECOMMENDATION: * **************************************************************** When a client sends a GIOP request that contains references to different versions of classes than what the server knows, the server performs an FVD callback to the client to gather metadata about the classes. WebSphere Application Server for z/OS address spaces don't properly handle FVD callbacks. Instead, the connection from the remote server to the client is closed, and an FFDC exception will appear in the client log similar to the following: Exception in thread "ChannelFramework Threadpool : 0" java.lang.NullPointerException at com.ibm.ws.tcp.channel.impl.TCPConnLink.getRemoteAddress (TCPConnLink.java:418) at com.ibm.ws390.channel.ziop.ZIOPConnectionContext. getRemoteHost(ZIOPConnenctionContext.java:411) at com.ibm.ISecurityLocalObjectBaseL13Impl.

Problem conclusion
Code was fixed to allow WebSphere Application Server for z/OS client address spaces to properly handle FVD callbacks. APAR PI22382 is currently targeted for inclusion in Fix Packs 7.0.0.37, 8.0.0.10, and 8.5.5.4 of WebSphere Application Server. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980 In addition, please refer to URL: http://www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack PTF information.
