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

[Paul Ferraro (Jira)]

     [ https://issues.redhat.com/browse/WFLY-13538?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul Ferraro updated WFLY-13538:
--------------------------------
    Description: 
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+.

Now that jboss-parent includes profiles for multi-release jars, we can add a variant (found in Undertow) that uses VarHandle and MethodHandle to use on Java9+.
