Not having uses directives is asking for trouble, as some Lucene bundles
use classes from other Lucene bundles in their external API.

I can almost guarantee you that there will be other bundles providing
org.apache.lucene.* packages in the wild (our companny builds its own
non-Orbit Lucene 4.9, for example). IMHO, uses directives are absolutely
necessary to allow Equinox to wire the Lucene bundles consistently.

That being said, thanks for the effort of bringing Lucene 5.2.1 to
Orbit. Much appreciated.

Best wishes,

Andreas
