My personal favorite of the non-gcj VMs is JikesRVM.  It is quite
promising.

The factors I look at when evaluating the free VMs:

* Performance
* Platform coverage
* Debuggability

gcj scores well enough on all of these; and more importantly, in my
opinion, the other free VMs fall short on one of them.
