Update bundled JRuby to 9.1.2.0 fully working on Java 8

[p0deje]

@titusfortner @shs96c I'm not sure that's what you guys want, but I sort of managed to upgrade bundle JRuby version to 9k.

$ java -jar third_party/jruby/jruby-complete.jar -version
jruby 9.1.2.0 (2.3.0) 2016-05-26 7357c8f Java HotSpot(TM) 64-Bit Server VM 25.45-b02 on 1.8.0_45-b14 +jit [darwin-x86_64]

$ java -jar third_party/jruby/jruby-complete.jar -S gem list

*** LOCAL GEMS ***

albacore (1.0.0)

I'm not sure if tasks are actually working (only checked //rb:unit-test), but now it fails with circular dependency:

$ ./go //rb:unit-test
...
go aborted!
Circular dependency detected: TOP => //rb:unit-test => //rb:android => //rb:common => //java/client/test/org/openqa/selenium/environment => //java/client/test/org/openqa/selenium/environment:environment => build/java/client/test/org/openqa/selenium/environment/environment.jar => //java/client/test/org/openqa/selenium/environment/webserver => //java/client/test/org/openqa/selenium/environment/webserver:webserver => build/java/client/test/org/openqa/selenium/environment/webserver/webserver.jar => //javascript:calcdeps => //javascript:calcdeps

I actually have no idea how to fix it and why it didn't fail before. It looks like javascript build depends on java build which depends on javascript build :)

Let me know if that is what you need (at least for the start) or if there is anything else I can do to help you.

Closing since there was no response.

@shs96c, will we want to upgrade for Selenium 4?
