True, but this is not black-and-white, but a matter of degree. Erlang processes also share memory: ETS. A crashed process could well leave an ETS table in an applicatively illegal state. So isolation is a scale. With Quasar we try to tip the scale closer to Erlang's isolation levels, but, as I've said, shared data structures could be extremely useful, too.
If fault-tolerance is your most important requirement, that far exceeds in its importance any other requirement, then by all means use BEAM. It was designed for precisely that kind of application.
If, however, fault-tolerance is just one of several important requirements, then the JVM will be the better choice in many circumstances.
