[jira] [Commented] (OPENEJB-1574) Check if a AVAILABLE state entry is in cache before throwing out the IllegalStateException.

["David Blevins (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENEJB-1574?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13047513#comment-13047513 ] 

David Blevins commented on OPENEJB-1574:
----------------------------------------

I think that's as good as it gets.  The concurrency of the Stateful container in general has been needing a rewrite.  So if this works, that's good enough.
