  attempting to set the position on a buffer.
  

Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED: WebSphere Application Server version 6.1     *
  *                 users of the raw body APIs of the HTTP       *
  *                 channel. This currently includes only the    *
  *                 ESI channel on z/OS but could include        *
  *                 customer channels.                           *
  ****************************************************************
  * PROBLEM DESCRIPTION: Callers of the getRawRequestBody API    *
  *                      might receive an IllegalArgument        *
  *                      exception.                              *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  There was a boundary condition that could lead to attempts to
  use the wrong buffer position information when slicing part
  of the HTTP message body out for the caller. This would cause
  the buffer to throw the IllegalArgument exception.
  

Problem conclusion

• The boundary condition is now checked for and handled correctly
  to avoid the exception.
  
  This is targeted for fixpack 6.1.0.1.
