[jboss-jira] [JBoss JIRA] (WFLY-13538) Add Java 9+ version of ConcurrentDirectDeque

[ https://issues.redhat.com/browse/WFLY-13538?page=com.atlassian.jira.plugi... ] Paul Ferraro updated WFLY-13538: -------------------------------- Description: The clustering code uses ConcurrentDirectDeque for its local scheduler implementation. While a portable implementation exists, a faster implementation that relies on sun.misc.Unsafe will be used when running with a compatible JVM. Now that jboss-parent includes profiles for multi-release jars, we can add a fast implementation (ported from Undertow) that uses VarHandle that will work on all Java9+ JVMs. was: The clustering code uses ConcurrentDirectDeque for its local scheduler implementation. While a portable implementation exists, there is also a faster version that relies on sun.misc.Unsafe. However, this only works in Java 8. Now that jboss-parent includes profiles for multi-release jars, we can add a variant (found in Undertow) that uses VarHandle to use on Java9+. -- This message was sent by Atlassian Jira (v7.13.8#713008)
