JES2 Storage exhaustion due to uncontrolled $JEWL creation/removal

Currently when an external task attempts to process a JES2 JOE and an error occurs, i.e. insufficient security access, JES2 builds a $JEWL control block for each JOE that was touched. The $JEWL is kept until one of the following conditions is met:

1) The requesting task retries and is successful
2) The requesting task ends successfully
3) The requesting task ends
4) JES2 terminates

If none of the conditions are met, JES2 will continue to process and will retain the $JEWL control blocks and eventually JES2 runs out of storage. This results in JES2 terminating with a "$HASP095 JES2 CATASTROPHIC ERROR. CODE = $GW4".

Once JES2 is restarted and if the external error is not resolved, this could be a recursive event. The repetitive loss of JES2 is not a healthy situation.
