I doubt using Java would really help in this case, because in order to use Java they would have to port the entire JVM to whatever platform they are using. Doing this without introducing any security bugs is about as difficult as just doing everything in C to begin with. By the way, the fact that the issue was with strncmp very strongly suggests that the issue was in C code.

Some security paper showed ARM disassembly of the issue, although I'm not sure if that was this specific issue or just another "strncmp-induced" issue.
(Btw. there are many smaller Java VMs for stuff like Java Card and JEFF)

They use ARC architecture and some embedded JVM. Of course this doesn't guarantee that the AMT web server runs on this JVM.
Few years ago somebody published analysis of the ME firmware for servers (desktop version was compressed with unknown algorithm). I'm sure you can google this for details.
> the fact that the issue was with strncmp
But we don't know for sure if it was strncmp. It's a logic bug, which can be implemented in any language. But again, maybe this server runs outside JVM and is written in C.
