Adrian Nistor created ISPN-2361: ----------------------------------- Summary: AbstractTxLockingInterceptor.lockKeyAndCheckOwnership() anomalies: can wait indefinitelly or it can wait too little due to spurious wakeups Key: ISPN-2361 URL: https://issues.jboss.org/browse/ISPN-2361 Project: Infinispan Issue Type: Bug Components: Transactions Affects Versions: 5.2.0.Alpha4 Reporter: Adrian Nistor Assignee: Adrian Nistor Fix For: 5.2.0.Beta1 When waiting for pending locks we can get into 2 cases that are not correctly handled: 1. The check for remaining time (remaining < 0) is incorrect because if remaining == 0 it will try to wait for transactions (waitForLockRelease) with 0 timeout (indefinitely). 2. CacheTransaction.waitForLockRelease() can return earlier than the specified timeout and the transaction might not yet be complete. This happens because the mechanism inside waitForLockRelease() does not protect itself from spurious wakeups leaving this to the caller. AbstractTxLockingInterceptor must be fixed to take care of this. -- This message is automatically generated by JIRA.
