Java. Which VM, which OS?
abw
We are trying to build a system dedicated to blind users based on a
capacitive touch panel and a few buttons (input), audio output and
network access. GUI support isn't mandatory. The software is written
in Java.
I am currently playing around with Angstrom on a C4 Beagleboard. Which
Java VMs are currently recommendable? I am also thinking about giving
other OSs a try (Android, Ubuntu?). There are tons of projects, proof
of concepts… any advice?
thank's,

I haven't got my hands on a Beagleboard as yet, but am very
interested in Oracle's Java 6 Embedded for ARM processors. The
requirements are at: http://www.oracle.com/technetwork/java/embedded/overview/sys-reqs-embedded-159989.html

I like 'jamvm'. The guys over at Bug Labs are likely to know the
best. Check out their forums[1] and work that was started back in
2008[2]. A more recent status update[3] shows that 'jamvm' can now
use the OpenJDK and recent commits to OE[4] show that 'shark-vm' can
be used.
Perhaps some of the Ubuntu experts could chime in with info on the
latest Java support there?

openjdk one although it's not exactly breaking any land speed records
- seems about 2x faster on a few little toy apps I tried. That at
least makes it feel in the same order as other similar applications.
When you spend most of your time on a 3.3ghzx6 core machine it's hard
to evaluate performance on something like the beagleboard objectively.
