tryLock with timeout allows simultaneous concurrent access to not thread-safe data to more then one client ---------------------------------------------------------------------------------------------------------- Key: JGRP-1679 URL: https://issues.jboss.org/browse/JGRP-1679 Project: JGroups Issue Type: Bug Affects Versions: 3.2.4, 3.3.4 Environment: Intel(R) Core(TM) i5-2310 CPU @ 2.90GHz 8 GB RAM Windows 7 JRE 1.6.31 Reporter: Architect SoftWeb.ISD Assignee: Bela Ban Fix For: 3.4 Attachments: lockservice_stability_testcase.jar It looks as it is possible to access a not thread-safe data simultaneously by several clients when tryLock with timeout is used. It is reproduced easily with timeouts from 1 to 3 seconds inclusive. It is very difficult to reproduce the issue with bigger values of the timeout.
