PROBLEM SUMMARY

USERS AFFECTED:
 All users of IBM WebSphere Application
Server using the proxy server with caching
and tracing enabled.

PROBLEM DESCRIPTION:
NullPointerExceptions are observed
when proxy server caching and tracing
are enabled.

RECOMMENDATION:
None

When caching is enabled on the proxy server a new HTTP message
object may be allocated that is not initialized.  A
NullPointerException occurs when the object is then used with
tracing.

PROBLEM CONCLUSION:                                             
The uninitialized request object will not be used.
