IcedTea on ARM relies on using either Gary Benson's work on Zero/Shark
to provide a port of HotSpot to the architecture or on using CACAO as
the VM instead with the OpenJDK class library.

I'm not sure how performance will compare with JamVM.  API
completeness of the class library will be better using the OpenJDK
class library over GNU Classpath, but Zero will definitely be much
slower.  I don't know if Gary has tried Shark on ARM yet and what the
results are.  CACAO and OpenJDK may be your best choice for now, which
means building IcedTea with ./configure --with-cacao.
