[infinispan-dev] stale persisted data?

Changing the topic as I have more info, and found that the problem is elsewhere.
First -- ClassResolver used does use SML, not not plain ML.
Stack trace was somehow misleading.
So, we're fine there, no false config used.
But, this is what I could find now.
This is my test (see below) - JPA over JDO over DataNucleus over GAE over CapeDwarf (long chain I know :-))
As you can see, I do cleanup afterwards, but ...
I run the same test twice, via ARQ, where I leave the name generation to ARQ:
10:49:08,684 INFO [org.jboss.as.server.deployment] (MSC service thread 1-1) JBAS015876: Starting deployment of "e9b7626a-361c-417d-80d5-b9e46af09f48.war"

2nd run:
10:51:20,686 INFO [org.jboss.as.server] (management-handler-thread - 5) JBAS018559: Deployed "6de03e61-ceb9-49d7-ad48-0f9edcc150ce.war"
Caused by: org.jboss.modules.ModuleNotFoundException: deployment.e9b7626a-361c-417d-80d5-b9e46af09f48.war:main

at org.jboss.marshalling.ModularClassResolver.resolveClass(ModularClassResolver.java:106)
As you can see, it tries to load some data from 1st deployment / test.
But since that's already undeployed, it's not found.
Shouldn't that JPA delete in finally block clean all stale data?
Trying to reproduce this now with smaller dep chain. :-)
