A preliminary version of DSP0203 2.2 contained a SIMPLEREQACK element for asynchronous operations which was removed before the final version. Support for SIMPLEREQACK should be removed from the Java CIM Client.
Patch sent for community review. During a 2 week period any exploiter may comment on the patch, request changes or turn it down completely (with good reason). For the time being the patch is part of the "Experimental" branch in CVS.
The community review is completed and we received no substantial criticism. Therefore the patch has been approved and merged into the "HEAD" branch. The next release will pick it up.
Found this comment in pywbem, seems about right:
The SIMPLEREQACK defines the acknowledgement response to a Simple
CIM Operation asynchronous request. The ERROR subelement is used
to report a fundamental error which prevented the asynchronous
request from being initiated.
<!ELEMENT SIMPLEREQACK (ERROR?)>

The patch was picked up by release 2.2.5 and will be closed.
