Is this on windows? There was a bug in 1.1.4 that caused the signing to
be ignored. There is a work around if you'd like it, otherwise I would
suggest you grab 1.1.5 which fixed the bug.

You get that by trying to do a System.getProperties or System.setProperties
call.

Currently that is not supported. The JDK only supports DSA, as we don't
have permission from RSA to include the necessary algorithms in the
JDK to parse jars signed with RSA. We are trying to work on a
solution for this...
