Description of problem:

It is currently impossible to have both lucene 4 and lucene 5 in the same OSGi runtime, due to the require-bundle directives being too relaxed in lucene 4. For example, I am seeing java.lang.VerifyErrors in Eclipse when I try this. Here is an example of such an error:

The problem is that the OSGi runtime is not wiring the expected version of lucene.core as a dependency of lucene.analysis. When you debug the OSGi runtime, you can see that it wires the newest possible version of org.apache.lucene.core as a dependency of org.apache.lucene.analysis_4.8.0

Requirement: osgi.wiring.bundle; filter:="(&(osgi.wiring.bundle=org.apache.lucene.core)(bundle-version>=4.8.0))"
Provider:    osgi.identity; osgi.identity="org.apache.lucene.core"; type="osgi.bundle"; version:Version="5.4.1"

While this is correct from an OSGi POV, it's this Lucene version mis-match that causes the above java.lang.VerifyError

When I fix the OSGi metadata in lucene 4 to make the require-bundle directive more strict, this error goes away and OSGi wires the dependencies as expected.
