[jboss-jira] [JBoss JIRA] (JGRP-1893) ENCRYPT: Thread safety issues during key changes

ENCRYPT: Thread safety issues during key changes ------------------------------------------------ Key: JGRP-1893 URL: https://issues.jboss.org/browse/JGRP-1893 Project: JGroups Issue Type: Bug Reporter: Tero Leppikangas Assignee: Bela Ban Fix For: 3.6.2 For symmetric encryption, ENCRYPT has members with shared state: secret key, version and ciphers. In order for to provide consistent state between different threads accessing these members, they should be synchronized. I have implemented one solution by wrapping the state in separate object which can be found here: https://github.com/tepitebson/JGroups/tree/ENCRYPT_Thread_safety I also have replaced the WeakHashMap holding the previous keys with Cache in google's guava library so my solution probably is not suitable for an official solution.
