We're getting a random test failure we're getting when testing rubygems against jruby, which shows a backtrace inside webrick's code.

Since the failure is specific to jruby, I tried running webrick tests against jruby.

Expected Behavior

webrick tests pass under jruby.

Actual Behavior

You can see the current failures on this WIP PR I opened at the webrick repo, where I just set up some changes so that the test suite at least runs properly.
