Fix Bootstrap to not call System.exit

Its not going to work: its blocked by security policy
and will just add a confusing SecurityException to the mix, and
bogusly give an exit status of 0 when in fact something bad happened.

Finally, if ES can't startup, it is a serious problem, there is
no sense in hiding the reason why: deliver the full stack trace.
