Subject [jira] [Commented] (DIRMINA-1118) NPE in SslHandler.checkStatus
Date Mon, 12 Aug 2019 12:11:00 GMT

    [ https://issues.apache.org/jira/browse/DIRMINA-1118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16905123#comment-16905123
] 

Christoph John commented on DIRMINA-1118:
-----------------------------------------

Side note: since the JDK upgrade we also have some test failures since we were using anonymous
cipher suites in one of the tests. Maybe this is related.

> 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.
