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:
