Offtopic: we should have some code to recognize these
options, I've seen some other code out there that uses
them. They should just map to -ms and -mx,
respectively.

Could you patch the method addToJarPackages:
....
        } catch (IOException ioe) {
            // silently skip any bad directories
            warning("skipping bad jar, '" +
                    (jarfile != null ?
                          jarfile.toString() :
                          jarurl.toString()) +
                    "'");
/** this is the patched line */
ioe.printStackTrace();
        }

and report back what the IOException is about, and
where it's thrown from?
