CLM 4.0.6 WAS compatibility
Upgrading to 4.0.6, and looking at the system requirements. Currently on WAS 7.x.23
https://jazz.net/wiki/bin/view/Deployment/CLMSystemRequirements405406#A5_Application_Servers
WAS 7.x.29+ is supported
http://publib.boulder.ibm.com/infocenter/prodguid/v1r0/clarity/prereqsForProduct.html
WAS 7.x.23+ is supported
So, do we need to upgrade WAS or not?
Accepted answer
https://jazz.net/wiki/bin/view/Deployment/CLMSystemRequirements405406#A5_Application_Servers is the official documentation.
On the other hand, http://publib.boulder.ibm.com/infocenter/prodguid/v1r0/clarity-reports/report/html/prereqsForProduct contains information that "is provided for informational purposes only. While efforts were made to verify the completeness and accuracy of the information contained in this publication, it is provided AS IS without warranty of any kind", and I would say it is not giving the correct answer in this particular case.
I would say in your scenario you need to upgrade WAS.

So I would go with this and should be the correct one
