[jira] [Comment Edited] (OPENJPA-2492) TestConcurrentMap error with
Java 8
[ https://issues.apache.org/jira/browse/OPENJPA-2492?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13973104#comment-13973104 ]

----------------------------------------------------------------------
we should surely only use ConcurrentMap (interface) and not concurrent hash map which has signature issues.
wdyt?
edit: an alternative is to implement ConcurrentMap ourself delegating to a ConcurrentHashMap (facade), this way signatures will be fine

> 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:
