****************************************************************
With Timebased Writes Enabled the PropertyWriterThread writes
out the session objects every couple of minutes. Under very
heavy load one of the customers noticed NullPointerExceptions
in the Standard Output logs. We were not able to recreate the
problem and we could not identify any possible window which
could have resulted in this exception being thrown. The user saw
this problem only once and does not have the environment any
longer for reproducing the problem.  Therefore, I am closing
this APAR without any code changes.
