Just as an FYI: we have removed the Java bindings from the 1.7.0 release due to
all the reported errors - looks like that code just isn't ready yet for
release. It remains available on the nightly snapshots of the developer's trunk
while we continue to debug it.
With that said, I tried your example using the current developer's trunk - and
it worked just fine.
I ran it on a single node, however. Were you running this across multiple
nodes? Is it possible that the "classes" directory wasn't available on the
remote node?
