The java rest client api 5.5.0 does not support scroll api? am i right?  
and I found java rest client api 5.6.4 support scroll api, can I use rest client 5.6.4 with cluster 5.5.0?  
by the way, my es cluster server is jdk8(es v 5.5.0), and my program client server is jdk7(rest client v 5.6.4), is this ok?

Yes. It should work.

High Level Rest Client can not work with Java 1.7

I'm biased. I'm working at elastic.

I prefer the official Rest Client because it's constantly updated and its source code is part of the elasticsearch repository. So we're sure it is tested everytime.
