methods.m: Emit sensible error message if Java not installed or classname does not exist (bug #65408)
* methods.m: Use try/catch block to test whether Java classname exists. If try
block fails, because Java is not installed or the classname does not exist,
then throw an error about the classname not being found. Add BIST test for
bug #65408.
