Description:

In one of Charles's blog posts, he mentioned that we should report it as a bug if JRuby 1.7 runs slower than JRuby 1.6.8 with java 7.
Here is the output of bench_red_black.rb with JRuby 1.6.8, and then with JRuby 1.7. Is it possible that I'm doing something wrong? Because lucid doesn't have a backport for java 7, I had to compile java 7 myself. I've had similar results with Oracle's java 7 as well.
