Error description

During long run tests with Websphere Service Integration Bus
(SIBUS), some exceptions show up and freeze the connection to
the SIBUS,leaving the first message in the queue locked .
.
FFDCs generated show the following exception:

* PROBLEM DESCRIPTION: NullPointerException from               *
*                      JSLocalConsumerPoint.unsetReady,        *
*                      preventing consumption of messages      *

****************************************************************
A field of the JSLocalConsumerPoint object was being accessed
from the JSLocalConsumerPoint.unsetReady() method, on another
thread, before the object was fully constructed.

The issue is most likely to occur when MDB applications
throw runtime exceptions wile consuming from a destination
with no exception destination configured. This is because
the blocking logic enabled when no exception destination
is configured for a destination accesses a list of
JSLocalConsumerPoint objects, which might include partially
constructed ones.

Problem conclusion

The fix for this APAR updates the
JSLocalConsumerPoint.unsetReady() method to prevent it from
attempting to access the uninitialized field.

The fix for this APAR is currently targeted for inclusion in
fix pack 6.1.0.33.  Please refer to the Recommended Updates
page for delivery information:
