CWWKZ002E headRegion must not be null
Recently had a power outage and my Jazz Team Server is down. When the applications load, it produces the error:
[ERROR ] CWWKZ002E: An exception occurred while starting the application X. The exception message was: com.ibm.ws.container.service.MetaDataException: java.lang.IllegalArgumentException: The headRegion must not be null.
X = the application (e.g. jts, qm, dm, etc.)
Accepted answer
I resolved this with the IBM helpdesk, here is the attempts and resolution:
Attempt: c:...\server.startup.bat -clean feature, but it did not resolve the headRegion issue.

I had this problem yesterday.
The fix was similar, bus a bit different. <o:p> </o:p>
- stop the service (if not already stopped) <o:p> </o:p>
- rename c:\Program Files\IBM\JazzTeamServer\server\liberty\servers folder <o:p> </o:p>
- Run server.startup.bat, wait for it to reconfigure the CLM <o:p> </o:p>
- Run server.shutdown.bat after CLM starts <o:p> </o:p>
- copy the config files from clm folder out the renamed servers folder to the new clm folder in the new servers folder. <o:p> </o:p>
e.g. bootstrap.properties, jvm.options, server.xml, maybe some more depending of your config <o:p> </o:p>
- start the service <o:p> </o:p>
<o:p> </o:p>
Another idea maybe just to delete the workarea folder in servers\clm folder. <o:p> </o:p>
Are you using Liberty or not?
According to the post:
https://developer.ibm.com/answers/questions/372957/i-had-a-server-power-outage-affecting-netcool-impa.html
Liberty Java class could be corrupted due to the power failure.
Based on the above suggestion, you may try:
1) Stop the Liberty Server
2) Restart the server with the --clean option
installeddir/ wlp/bin/./server start --clean
3) After it has restarted you can stop the server again
installeddir/ wlp/bin/./server stop
or kill the process
4) Start the servers as normal
