["Romain Manni-Bucau (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENJPA-2492?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13973104#comment-13973104 ] 

Romain Manni-Bucau commented on OPENJPA-2492:
---------------------------------------------

we should surely only use ConcurrentMap (interface) and not concurrent hash map which has signature issues.

wdyt?

> One more test failure while running with Java 8.  Since Java 8 introduced some new methods on the Map interface, this is probably related.  We are getting a VerifyError related to the keySet signature:
