Problem summary

****************************************************************
* USERS AFFECTED:  IBM WebSphere Application Server version    *
*                  7.0 users of servlet caching.               *
****************************************************************
* PROBLEM DESCRIPTION: java.lang.StackOverflowError occurs     *
*                      when servlet caching is enabled.        *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
A java.lang.StackOverflowError might occur if the
requesting URI is just the context root and any filter is in
place.
When a request is made to the context root, it will be
forwarded to the available welcome file.  During that
process, sometimes the fragment might be cached incorrectly.
It causes the cached URI of the child and the parent to be the
same.  The next request to the same URI can get into a loop
and eventually a StackOverflowError occurs.

Problem conclusion

A new custom property is being introduced,
com.ibm.ws.cache.CacheConfig.ignoreFilterProxyServlet.  When
this custom property is defined and set to true, dynacache
servicing is bypassed and the caching of parent and child
fragments with the same URI is avoided.

This custom property must be set as a JVM custom property and
will affect all servlet cache instances.

APAR PM53882 is currently targeted for inclusion in
Service Level 7.0.0.25 of WebSphere Application Server V7.0.
