Closed as program error.
Error description
The symptoms for this APAR are similar to APAR IC79441. The WMQ FTE agent process fails with a java.lang. NullPointerException. The following stack is evident in the FTE agent FDC file Method: uncaughtException Probe: ABEND_001 Cause: java.lang.NullPointerException . While this has the same symptoms as APAR IC79441, it is actually has a different root cause. It seems that because the agent ended uncleanly before making its first transfer checkpoint, we throw a NullPointerException as observed in the ABEND file. This is because the code does not take account for the situation whereby the transfer may move to state RUNNING but to complete no checkpoints. During recovery we expect a checkpoint, and so throw the NullPointerException.
Local fix
Problem summary
If an agent failed without having made any checkpoints for a given transfer, and had already moved the transfer into RUNNING state, the agent would never be able to recover and would log a NullPointerException ABEND on every attempt to start. USERS AFFECTED: All PLATFORMS AFFECTED: All
Problem conclusion
The code has been altered to cater for the window in which no checkpoints have been made for a given transfer. In this situation transfer of the file will restart from the beginning. The fix for this APAR is currently targeted for inclusion in fix pack 7.0.4.2.
