Issue created: https://issues.apache.org/jira/browse/FELIX-2077
By the way, I was meaning more than the fact an OSGi bundle's Manifest
contains special entries. It seems that the Manifest should be placed
somewhere special in the archive file (not sure this is bundle-specific). My
broken bundles were plain working bundles that I had 1. unzipped, 2.
modified the Manifest and 3. compressed again as a Zip file, changing the
extension. It seems that the "jar" utility does more than just zip the
contents of the file.
