Hello, I'm trying to execute concurrent add,remove over a Collection for a
TreeAOPCache with multiple members. I'm finding some problems that leave the Caches at
inconsistent state.
I've created a version of testConcurrentPut() method fot TreeAOPCache to be executed
at:
org.jboss.test.cache.test.standAloneAop.ReplicatedTxAopTest
The method adds a new value at the same collection for distinct Cache members. The TX
commit replication doesn't commit successfully but there aren't any Exception thrown.
The "tester" Cache finish with "languaje" German and the "tester1" cache finish with
"languaje" English.
Probably I'm missing something important or is this a TreeCacheAOP limitation?. Is
there a better way of working with collections at TreeCacheAOP?. Thank you.
