[infinispan-issues] [JBoss JIRA] Reopened: (ISPN-1340) ReadCommittedLock - commited Cache.remove is not visible to other transactions

Marcel König reopened ISPN-1340:
--------------------------------



Sorry, I think I made a mistake in describing the problem. The first put should be commited. 
Please see the unit test.

In the Unit Test:
1. cache.put("k","v")
2. tx1 begin + cache.get("k") == "v"
3. tx2 begin + cache.remove("k")
4. tx1 cache.get("k") == "v"
5. tx2 commit
6. tx1 cache.get("k") == "v" but should be null

In our application we do the first put in an own sub transaction (REQUIRES_NEW) of tx1 so that the put should be commited. Perhaps I should change the unit test to do the put in an own transaction like tx0.
