****************************************************************
When a JAX-RPC web service is invoked, a
java.lang.StackOverflowError similar to the following may
occur:

java.lang.StackOverflowError
at java.util.Hashtable.get(Hashtable.java:482)
at
com.ibm.ws.webservices.engine.utils.LockableHashtable.get(Lockab
leHashtable.java:140)
at
com.ibm.ws.webservices.engine.utils.LockableHashtable.get(Lockab
leHashtable.java:142)
at
... there are a large number of repeated calls to the method
... LockableHashtable.get()
at
com.ibm.ws.webservices.engine.utils.LockableHashtable.get(Lockab
leHashtable.java:142)
at
com.ibm.ws.webservices.engine.MessageContext.getProperty(Message
Context.java:1337)
at
com.ibm.ws.webservices.engine.MessageContext.getPortName(Message
Context.java:2180)

This error may occur after the web service is called several
times.

Problem conclusion

The StackOverflowError is due to an accumulation of
LockableHashtable objects after multiple calls to the JAX-RPC
web service.  The accumulation is due to a code path that
inadvertently avoids a cleanup of these objects.  The code is
changed to ensure that the cleanup occurs.

APAR PK86465 has similar symptoms as this APAR.
This APAR, PK96999, will fix both problems.

The fix for this APAR is currently targeted for inclusion in
fix packs 6.0.2.41, 6.1.0.29 and 7.0.0.9.  Please refer to the
