I think it's a little more involved than that.  It's been a while
since I looked at the launcher code much, but as far as I remember it
tries to launch the JVM in-process rather than spawning a new one.
There's some fallback to spawning a new process to handle 32-bit /
64-bit switching, which should get logged somewhere.  I assume that's
also enabling the JVM process to launch from the emulated code in this
case.  How reliable that is I don't know.

Best wishes,

Neil
