The error is present in EAP Clustering tests where HTTP session data is replicated;
We spotted the error in 2 kind of tests:
- tests with replicated cache where fail-over is introduced by shutting down nodes
- tests with replicated cache where fail-over is introduced by shutting down nodes and replication level is granular
- tests with replicated cache and shared-sessions where fail-over is introduced by jvmkill
- tests with replicated SFSB
In the first kind of tests the nodes are configured as follows:
embed-server --server-config=standalone-ha.xml /subsystem=jgroups/channel=ee:write-attribute(name=stack,value=tcp) /subsystem=infinispan/cache-container=web/replicated-cache=testRepl:add() /subsystem=infinispan/cache-container=web/replicated-cache=testRepl/component=locking:write-attribute(name=isolation, value=REPEATABLE_READ) /subsystem=infinispan/cache-container=web/replicated-cache=testRepl/component=transaction:write-attribute(name=mode, value=BATCH) /subsystem=infinispan/cache-container=web/replicated-cache=testRepl/store=file:add() /subsystem=infinispan/cache-container=web:write-attribute(name=default-cache, value=testRepl)
In the second kind of tests the nodes are configured as follows:
embed-server --server-config=standalone-ha.xml /subsystem=jgroups/channel=ee:write-attribute(name=stack,value=tcp) /subsystem=infinispan/cache-container=web/replicated-cache=testRepl:add() /subsystem=infinispan/cache-container=web/replicated-cache=testRepl/component=locking:write-attribute(name=isolation, value=REPEATABLE_READ) /subsystem=infinispan/cache-container=web/replicated-cache=testRepl/component=transaction:write-attribute(name=mode, value=BATCH) /subsystem=infinispan/cache-container=web/replicated-cache=testRepl/store=file:add() /subsystem=infinispan/cache-container=web:write-attribute(name=default-cache, value=testRepl)
In the fourth kind of tests the nodes are configured as follows:
embed-server --server-config=standalone-ha.xml /subsystem=jgroups/channel=ee:write-attribute(name=stack,value=tcp) /subsystem=infinispan/cache-container=web/replicated-cache=testReplWeb:add() /subsystem=infinispan/cache-container=web/replicated-cache=testReplWeb/component=locking:write-attribute(name=isolation, value=REPEATABLE_READ) /subsystem=infinispan/cache-container=web/replicated-cache=testReplWeb/component=transaction:write-attribute(name=mode, value=BATCH) /subsystem=infinispan/cache-container=web/replicated-cache=testReplWeb/store=file:add() /subsystem=infinispan/cache-container=web:write-attribute(name=default-cache, value=testReplWeb) /subsystem=infinispan/cache-container=ejb/replicated-cache=testReplEjb:add() /subsystem=infinispan/cache-container=ejb/replicated-cache=testReplEjb/component=locking:write-attribute(name=isolation, value=REPEATABLE_READ) /subsystem=infinispan/cache-container=ejb/replicated-cache=testReplEjb/component=transaction:write-attribute(name=mode, value=BATCH) /subsystem=infinispan/cache-container=ejb/replicated-cache=testReplEjb/store=file:add() /subsystem=infinispan/cache-container=ejb:write-attribute(name=default-cache, value=testReplEjb)
The error happens after the nodes are restarted:
