Jakob Homan commented on SAMZA-455:
-----------------------------------
If we end up deciding to go with something like Eric's proposal - which I
support - we should update the website with a special section explaining the
plan. This will help to provide that solid warning Eric recommends, as well as
give new contributors an idea of where we're headed.

> Currently Samza builds against JDK 7, although AFAIK we are not yet using
> JDK7-only language/stdlib features, so we could still support JDK6 if we want
> to. There have been requests for this:

> boundary) on which JDK versions to support. There was a general desire to
> start moving towards JDK8, so that we could start using Java 8 language
> features and gradually start moving away from Scala. But we can't use Java 8
> language features as long as we're still supporting JDK 6 and JDK 7, and the
> day when everyone is using JDK 8+ still seems fairly far in the future.
> JDK 6 was [EOL in Feb
> 2013|http://www.oracle.com/technetwork/java/eol-135779.html], but if there is
> continued demand for it, perhaps we should continue supporting it. The
> counter-argument is that "JDK6 seems to be becoming the Windows XP of the
> Hadoop ecosystem", as [~jghoman] put it.
> So: should we switch Samza back to building on JDK 6? And if so, can we
> decide on a policy for removing JDK 6 support?
