It's been a while, but I did test cacao and jamvm before as better alternatives
to the default Zero jvm. My conclusion back then was that they're not really
practically usable except for test or toy programs.
Even longer ago, I did use the IBM jdk 6 on powerpc and that one was actually
usable. This one would most likely still have the best performance of the
available jdks on powerpc. Version 7 of the jdk is available, but it does not
seem to work on Apple hardware (G4).
Regarding arm hardware, there is an embedded jvm available from Oracle,
thanks to the popularity of the Raspberry Pi. I did not test that one however.
Either way, I gave up on using java on my powerpc laptop. It is simply too slow
to do any useful programming in java with it. I think that clojure and
be even slower.
