[orbit-dev] Help! Stuck in "uses" heck in the Batik bundles

[Christian Damus <cdamus@xxxxxxxxxx>]

Hi,

Any help will be greatly appreciated,
because I think I'm lost in the OSGi details.

In the environment in which I have been
working on the Batik bundles, I have had no issues with OSGi's dependency
resolution.

However, in an environment that has
the org.w3c.dom package contributed by Xerces as well as by the JRE (I
think), OSGi fails to resolve the following packages:

  - org.apache.batik.dom.svg (in
the bundle of the same name)
  - org.apache.batik.dom.util (in
the org.apache.batik.dom bundle)

because of a conflict in the "uses:=org.w3c.dom"
directive in the exports of the above packages.  I thought that the
"uses" directive was supposed to help OSGi to create a consistent
classpath because various Batik bundles import org.w3c.dom without any
version range (given the uncertainty of versions out there in JREs).

I have tried the new Organize Imports
support for computing "uses" directives.  All that it does
is to add a bunch more packages to the "uses" and the problem
actually gets worse.

The problem seems to go away when I
remove these "uses" directives, but I don't know what potential
ill effects *that* will have.  I don't know what the correct resolution
is.

Any ideas?

I have raised https://bugs.eclipse.org/bugs/show_bug.cgi?id=178431
to track this problem.

Thanks,

Christian
