At runtime when I am trying to access the cache (distributed). Then I get following exception. Accessing same cache works fine from other JVM where different app is deployed. Please help in giving any pointers as to why I am getting following exception. I am using 5.1.6 version.

I found following where this same error is discussed. But, not sure whether it is happening same way as it's happening for me. However, it says that fix is available in version 6.0. Can someone please confirm?
