VMs

Recently, BEA acquired Appeal Virtual Machines and their server VM
JRockit (http://www.jrockit.com) and obviously changed the licensing:

<quote>As of the aquisition, the JRockit Virtual Machine is available
for free! Now everyone can benefit from superior Java performance on
Intel platforms.</quote>

So if this means that everyone can use the JRockit VM as a free
alternative, I wonder whether anyone has experiences with it and its
speed and stability. They claim to have optimized it for server usage,
so there should be advantages to the "standard" VMs.

To the best of my knowledge, there are currently the following relevant
J2SE VMs for Windows and Linux, all of them free of charge:
- Sun HotSpot Client VM 1.3.1/1.4: Windows, Linux;
- Sun HotSpot Server VM 1.3.1/1.4: Windows, Linux;
- IBM VM 1.3.0: Windows, Linux;
- Blackdown VM 1.3.1: Linux;
- JRockit VM 3.1 (implementing J2SE 1.3): Windows, Linux.

Appeal claim to beat the IBM VM in terms of SPECjbb2000 results. Is
there anyone who runs Resin on JRockit and has compared it to other VMs?
Besides, anyone having performance comparisons between the Sun VMs and
the IBM VM on the same machine?
