[infinispan-issues] [JBoss JIRA] (ISPN-2164) Return value of Cache.remove(key) not consistent in transactional context

Return value of Cache.remove(key) not consistent in transactional context ------------------------------------------------------------------------- Key: ISPN-2164 URL: https://issues.jboss.org/browse/ISPN-2164 Project: Infinispan Issue Type: Bug Components: Core API, Transactions Affects Versions: 5.1.5.FINAL Reporter: Carsten Lohmann Assignee: Galder Zamarreño Labels: jdg, jdg6 Fix For: 5.2.0.FINAL I have a scenario where multiple threads attempt to remove the same key concurrently via "cache.remove(key)" (each thread having explicitly started a transaction). I expect only one thread to succeed, ie. only one invocation of "cache.remove(key)" to return a non-null value. But that is not the case, the return value of "cache.remove(key)" is non-null for more than one thread. In that sense, "cache.remove(key)" seems to behave differently from "cache.remove(key, value)". The bug can be reproduced by using a test analogous to the one in "DummyTxTest" (ISPN-2077), but using "cache.remove(key)" instead of "cache.remove(key, value)".
