Title: Don't set 1.9.2 suckage constant when on JRuby. JRuby don't suck.

I opted to just do a hard defined?(JRUBY_VERSION) check since the suckage flag should never be set on JRuby.

I also respectfully request this be ported to 1.8 branch, since that's what we're running off for 1.6.x and master.

Fixes #268.
