Type: Bug
Resolution: Done
Priority: Major
Fix Version/s: 9.0.0.Final
Affects Version/s: 5.3.0.Final, 6.0.0.Alpha4
Component/s: Cross-Site Replication
Labels:
None

Steps to Reproduce:

Hide

Create a 6.0 alpha configuration with x-Site enabled for a specific cache using at least 2 different nodes in separate clusters using only the TCP protocol for both the local and x-site clusters. Next post a value into the local cache on one site (this will occur w/o error), the remote site will however exhibit the RPC exception when the x-site replication occurs. Note: It does not matter what transport is used for the cache as it has been verified to occur with REST and Hotrod

Description

The following can be referenced from forum post by Chris Riley ISPN000071

Trying to perform an insert of a cache value into a distributed cache that is replicated via Cross Site Replication in JBoss 6.0.0.Alpha4. The cross site replication has two nodes in the global cluster.

When a value is put on the local site we get the following error on the remote site. We just upgraded to 6.0.0.Alpha4 because of JIRA ISSUE ~~ISPN-3346~~, which we reproduced in 5.3.0.Final. I have attached our jboss configuration file for review.
