Removing the -Djruby.jit.threshold=0 flag, which seems to have been introduced due benchmarking. Removing the force of AOT means a noticeably faster startup (we do not need to 'compile' every method we bump into). The JIT threshold default is 50 in JRuby 9.2/9.3, there might be other heuristics in the future to better determine hot methods.
