Please read the attached text from the uima dev-mailing list with the subject:
[UIMA eclipse plugins] Possible WRONG wiring between UIMA Eclipse plugins

------------------------------ Copy from uima dev-mailing list

This issue is not unique to OSGi. The package name collision can be happen also
to the Java program that uses multiple Jar(s) in the classpath.
Having "Import-packages+Provider Selection" is not well supported by Eclipse's
tooling and (I think) can be over-designed.
Since this is a "rare" situation that can be occurred among the developers in
the "org.apache.uima" domain, I have the tendency to keep the current
specification as it is. Maybe, we just document it as a reminder at somewhere
(just in case there are some plugins that re-define the
"org.apache.uima.jcas.tcas").

OSGi does provide a mechanism to have the import-package include
specifying which bundle it should come from. See section 3.6.8
"Provider Selection" in the r4.core.pdf doc for OSGi for details.
The POMs we use don't generate this though. Do you see that allowing
multiple bundles to export the same package name, and then having our
configuration be more explicit about which bundle to wire to, is (or may
be) a design requirement?

> Project: UIMA
> Issue Type: Bug
> Components: Eclipse plugins
> Affects Versions: 2.2.2AS, 2.2.2S
> Reporter: Mikhail Sogrin
>
> Eclipse plugin org.apache.uima.runtime previously contained jars inside a
> plugin. Version 2.2.2 has jars unzipped. But contents of
> uima-document-annotator.jar were not added to 2.2.2 plugin.
> I've previously submitted a report (UIMA-400) about the same jar which was
> not added to 2.1.0 plugin by mistake, and it was fixed in 2.2.0, and now
> broken again in 2.2.2.
> In addition, there's a circular dependency for the package
> org.apache.uima.jcas.tcas, i.e. the same package is exported and imported in
> manifest. Probably, it's caused by the same missing classes from that jar.
