Ruwan Linton updated SYNAPSE-339:
---------------------------------

         Priority: Blocker  (was: Major)
    Fix Version/s: 1.2

This issue is caused by an issue in the wso2-caching and I am in the process of 
getting a new release of this from wso2 with a fix to get this fixed. I hope it 
will be available as a point release soon and with that we can fix this issue 
for the 1.2 release
