Chris Riccomini commented on SAMZA-455:
---------------------------------------
Personally, I'm OK with going back to supporting JDK6 for both compile and
runtime. No one really argued for it before, but if there are folks that want
it, I'm OK with it. The code already compiles and runs in JDK6, we just have to
do releases with it.

> 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

> 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?
