I've had good experiences with several jruby on rails apps under tomcat using warbler and they all seem to perform fine with config.threadsafe! enabled. You should probably investigate those stacktraces, maybe they were caused by unthreadsafe gems or application code?

It would fail without using any gems other than trinidad. I'll try to reproduce it tomorrow.

I'm rerunning it now with the latest rails and latest jruby and all is good.
