Slightly better/cleaner might be to use Procedure:

   Procedure test = (Procedure) env.get( "test", null );
   test.apply0();

Though I think it unlikely that user-defined functions
will no longer be ModuleMethod, it is even less likely
that they will cease being Procecedures.  In any case,
using Procedure also works for builtin or halt-written
procedures.

You might also consider using 'eval' instead of 'get':

   Scheme scm = Scheme.getInstance();
   // or scm = new Scheme();
   Procedure test = (Procedure) scm.eval("test");

This is slower than using get (though it doesn't matter
unless its in an inner loop), but you don't have to
explicitly work with environments.
