Major Description
Currently the sling parent pom uses the maven-bundle-plugin in version 3.0.1 but defines a dependency on bndlib in version 1.50.0.
Since maven-bundle-plugin 3.0.1 uses bndlib in version 3.0.0 anyhow the dependency in parent should also be increased to that version.
Otherwise you at least get the wrong impression, because e.g. in bndlib 1.50.0 the aQute.bnd.annotation.ProviderType is being marked as being the default in the javadoc while in reality the maven-bundle-plugin uses bndlib in version 3.0.0 where aQute.bnd.annotation.ConsumerType is the default (see also https://github.com/bndtools/bnd/commit/5935e70ba990e40a95e14fb932158ebf8d2225fe).
Also additional interfaces being added in 3.0 cannot be used.
