Problem summary

****************************************************************
* USERS AFFECTED:  Users of IBM WebSphere Application          *
*                  Server V7.0 who turn on the                 *
*                  AutoDecompression feature of the HTTP       *
*                  Channel.                                    *
****************************************************************
* PROBLEM DESCRIPTION: Buffers in the HTTP Channel may         *
*                      become corrupted when                   *
*                      AutoDecompression is configured "true"  *
*                      Default is false.                       *
****************************************************************
* RECOMMENDATION:  Do not configure AutoDecompression for the  *
*                  HTTP Channel for V7.0.0.0 - 7.0.0.5         *
****************************************************************
When the custom property of AutoDecompression is set to "true"
for the HTTP Channel, there was a logic bug which would allow
a buffer to get used when it was the wrong buffer to use
internally.  These resulted in an internal buffer corruption
which then resulted in an error/exception later on.  The error
or exception could vary, since it depends on how the buffer is
used later on.

Problem conclusion

The logic error was fixed so that the correct buffer was used
internally.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.7  Please refer to the Recommended Updates page
for delivery information:
http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980

Temporary fix

Do not make us of the HTTP Channel custom property of
"AutoDecompression"
