[jboss-jira] [JBoss JIRA] Closed: (JBCL-20) Don't use CopyOnWriteArraySet for caching and blacklisting

Don't use CopyOnWriteArraySet for caching and blacklisting ---------------------------------------------------------- Key: JBCL-20 URL: https://jira.jboss.org/jira/browse/JBCL-20 Project: JBoss ClassLoader Issue Type: Task Components: ClassLoader Affects Versions: JBossCL.2.0.0.Beta12 Reporter: Adrian Brock Assignee: Adrian Brock Fix For: JBossCL.2.0.0.CR1 According to the javadoc CopyOnWriteArraySet is not designed for large sets. I'm seeing slow calls to blacklist.contains(className) in JBossAS Instead use a ConcurrentHashMap (effectively only the key side).
