This exception was printed, but the exception itself was caught and is begnin (that is, it does not affect the runtime system in any way).Problem conclusion A null check is now made, so a NullPointerException will not be generated under these circumstances The fix for this APAR is currently included in fixpack for WebSphere Business Integration, release 5.1.1, cumulative fix 3Temporary fix Comments
