Subject Re: Recent ZK Jenkins failures due to SSL protocol changes on central

Hi Patrick,

In my opinion terminating support for java 1.6 is a good idea. Even it's
extended support will end this year (
http://www.oracle.com/technetwork/java/javase/eol-135779.html).
And the projects I've seen are all updated from java 6 by now, especially
as more and more libraries and components are discontinuing support for 1.6
(WebSphere, just to name one).

Regards,
Norbert
