[infinispan-issues] [JBoss JIRA] (ISPN-4702) The ForkJoin thread pool should be started lazily

[Dan Berindei (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-4702?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13011996#comment-13011996 ] 

Dan Berindei commented on ISPN-4702:
------------------------------------

The common pool is created the first time you create an {{EquivalentConcurrentHashMapV8}}, and it can't be stopped. 
But AFAICT it doesn't create any worker threads until something is submitted to the pool, just like {{ThreadPoolExecutor}}.

> We should at least start this pool only on-demand, and ideally shut it down after a grace period if it's no longer being used.
