PM19534: An OutOfMemoryError error occurs due to excessive SOAPElement objects while using Spring.

Fixes are available

APAR status

Closed as program error.

Error description

The WebSphere Application Server may issue an OutOfMemoryError
error when decrypting a SOAP message.  The customer is using
Spring to decrypt the message.  The message uses the SAAJ api
provided by the WebSphere Web services runtime.

The heapdump produced when the OutOfMemoryError occurs
indicates that most of the memory is consumed by
com.ibm.ws.webservices.engine.xmsoap.SOAPElement objects.

****************************************************************
The customer's use of the Spring framework has exposed a
problem in the IBM implementation of SAAJ.

SOAP with Attachments API for Java (SAAJ) defines several
methods to add a SOAPElement as a child to an existing parent
SOAPElement.  If the new SOAPElement is already a child of the
parent, the SAAJ implementation is required to remove the
prior child.

In some cases, the IBM implementation failed to remove the
prior child from the tree.  This failure to remove the prior
child resulted in a SOAPElement containing a large number of
child SOAPElements representing the same data.  Eventually
this causes an OutOfMemoryError to occur.

This problem could occur with customers who do not use Spring.

Problem conclusion

The root of the problem is due to the IBM SAAJ runtime failure
to remove a prior instance of a SOAPElement when a new
SOAPElement is added.

The algorithm to detect the prior instances of the same
SOAPElement is improved.

The fix for this APAR is currently targeted for inclusion in
fix packs 6.1.0.37 and 7.0.0.15.  Please refer to the
