Congratulations… The new 4.0.0-rc1 version looks much better, but unfortunately the OSGi community is still unable to use Smack properly. The correct “Bundle-Version” in the manifest file must be “4.0.0.rc1” not “4.0.0-rc1”. A dash is disallowed in this entry and invalidates your bundles. Please refer to: http://www.osgi.org/Download/File?url=/download/r5/osgi.core-5.0.0.pdf.
Please fix it.
