I assume that was a custom VM. As far as I know, there is no way to disable GC in the official Oracle JVM.

Can you do this with real-time Java? I understand that it allows you to do all your memory allocation first, then switch into real-time mode with no GC. http://www.oracle.com/technetwork/articles/java/nilsen-realt...

I'm pretty sure it was a custom VM: I wasn't on the team, but my own group (Unix) was playing with custom IP stacks with the same goal (reducing latency, increasing determinism).

With collectors like CMS, you can control after what percentage of the GC is filled GC will kick in. I think you can use that get the same effect. This is only for old gen.

I too would like to know that was the VM and how it was disabled.
