Christoph John commented on DIRMINA-1118:
-----------------------------------------
Sorry, editing comments does not work for me either. Don't know if it's my
browser or JIRA.
Anonymous cipher suites are disabled by default in the JDK now, that is why our
tests were failing.
> NPE in SslHandler.checkStatus
> -----------------------------
>
> Key: DIRMINA-1118
> URL: https://issues.apache.org/jira/browse/DIRMINA-1118
> Project: MINA
> Issue Type: Bug
> Affects Versions: 2.1.3
> Reporter: Christoph John
> Priority: Major
>
> Since some days we receive this NPE on our build server when running tests.
> Interestingly this occurs since OpenJDK has been switched from 8.192 to
> 8.222. However, it is probably just coincidence.
