strmpnk beat me by 7 minutes, here's a link to the Erjang project: https://github.com/trifork/erjang

It's not really "BEAM on the JVM", it's actually a translator of BEAM compiled code to JVM bytecode. But the concept is similar, the target for Erlang is important, but so far a variety of things have been used. JAM was the original VM, later BEAM, later BEAM with HiPE. See [1] for some more information. There was also, apparently, an Erlang-to-Scheme translator. It'd be interesting (does this exist yet?) to see someone implement Erlang semantics in Racket.

While it's true that Erjang translates BEAM code, BEAM itself also does this to yet another more modern internal code (. I'd still consider both BEAM implementations.
