-----------------------------------------

It would be nice to have the fix in the next EAP CR. When is the 3.2.0.GA scheduled for? Cheers.

> While running web session replication soak tests, we ran into the following failure using synchronous buddy replication.
> The issue, I think, resides in the LegacyDataGravitatorInterceptor.ResponseValidityFilter, the purpose of which is unclear to me.  It does not actually filter out invalid responses, since ResponseValidityFilter.isAcceptable(...) always returns true.  Consequently, the response processing in LegacyDataGravitatorInterceptor.gravitateData(Fqn) throws an ClassCastException if a response is not a GravitateResult instance, which was the case in the trace below:
> 17:42:30,454 ERROR [org.apache.catalina.connector.CoyoteAdapter] (ajp-jawa03%2F10.34.32.155-8009-141) An exception or error occurred in the container during the request processing
