Type: Bug
Resolution: Done
Priority: Major
Fix Version/s: JDG 7.2 DR1, JDG 7.2 GA
Affects Version/s: JDG 7.0.0 GA
Component/s: Cross-site Replication
Labels:
None

Fix Build:
DR1
Target Release:

JDG 7.2 GA
Git Pull Request:
https://github.com/infinispan/jdg/pull/1180
Steps to Reproduce:
Hide

Attached a JDG 7 domain mode configuration which consists of 4 nodes on a single host.

SiteA

server-a1

server-a2

SiteB

server-b1

server-b2

You can start the domain any directory you like.

mkdir domain; cd domain unzip configuration.zip $JDG7_HOME/bin/domain.sh -Djboss.domain.base.dir=./

Just starting the domain will be enough to reproduce the ClassCastException. Or you can restart a node to make it happen again.

[domain@localhost:9990 /] /host=master/server-config=server-b2:stop [domain@localhost:9990 /] /host=master/server-config=server-b2:start
