We took the approach of loading in the dependencies from within Java,
and configuring a ClassLoader appropriately:

    http://oss.sygneca.com/javarun

This has been far more reliable than trying to specify the classpath
externally. Particularly so in awkward environments such as Cygwin,
but even on Linux we were previously getting strange problems with
classes apparently randomly failing to load, which we can only
attribute to JVM bugs.

Javarun expects a list of dependencies to be provided in a file one
per line, but it could easily be modified to read sbaz descriptions.
