Yeah, people fail to realize it was not designed to speed up a JIT, but speed up an interpreter, as most of the Java ME/SE ARM VMs at the time were interpreters. I have my doubts it would succeed at that, but at least it was clearly designed to do that.
By the time you could start doing full desktop OSes and full Java VMs on small ARM chips, Jazelle (DBX) had been stubbed out completely for years, handling only the most simple of opcodes or even none at all.
