+1 for me too.
Java 9 is already in early access and is supposed to be GA fairly soon.  I think the last
time we talked about this we decided that staying 1 release of java behind the latest was
decent practice, and I still agree. - Bobby

As Jungtaek has already mentioned Oracle stopped supporting JDK/JRE 7 since April 2015. Java
8 brings better APIs and it will make our code look better and future user APIs can be designed
lot better.

I'm not sure we would like to continue discussion on cross mailing list. Please let me know
if we want to split discussion into two separate thread per mailing list.
I'm +1 on dropping Java 7 support on master (2.0.0).
While porting clojure code to java 7, we needed to convert functional style functions to for
loop which is too verbose and hide intention. It also drops productivity. We can do similar
style by using Guava but it's more verbose, and Guava is one of libraries I don't want to
add as dependency. (Not only storm-core, but also other modules.)
I'm not sure how much users are forced to not use Java 8. (This is common concern of upgrading
JDK version.) At now, Java 8 is over than 2 years ago, and Oracle drop public support of
JDK/JRE 7 1 year ago. Furthermore, Java 9 will be released to next year. (actually planned
to this year) 
I'm also the one who need to take a deep look at Java 8, but I think the time has come. Let's
go for that.

Hi All,
      Dropping java 7 support on master will allow us to use the new api in
Java 8 and since the master is being used for java migration its good to
make the decision now. Let me know your thoughts.
