N/A, the error can be ignored

It is present due to a small timing window that may be encountered when attempting to deactivate an instance of the WorkProfilerHAManagedItem which should not be active and will be subsequently deactivated in another code path. The WorkProfilerHAManagedItem is always started and quickly learns that it should be deactivated because there is a better process to run the WorkProfilerHAManagedItem. The deactivate encounters the exception because the process is not yet completely initialized. As a result, the mbean is not deactivated immediately. However, subsequent processing will perform the same check and deactivate the process if it is not needed and at that time the deactivate will succeed because the initialization has completed.
Problem conclusion
The code was improved to remove the small timing window that causes the exception. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.13 and 9.0.0.6. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
Temporary fix
Ignore the error as it causes no problem.
