>From our experience, the complexity of multiple providers often arises by accident when tools like BND are used to merge lots of packages into single bundles. This can be a good feature in that it minimises the dependencies for the user to start a given bundle, but it the downside is it leads to very complex problems for the resolver to solve.
We've also found a lot of complex uses graphs in the bundles hosted in the spring repository as often you will find multiple bundles export javax.servlet.http (for example) - not sure if this is by accident or a requirement of the particular bundles. >From the point of view of resolution algorithms, I've put special logic into the sigil resolver to "prefer" bundles that have the fewest imports even if two bundles claim to export the same package - this often short cuts a lot of unnecessary graph walking where there are more than one possible provider of a given package. A spectacular example of this is the "com.springsource.org.aspectj.tools" bundle: http://www.springsource.com/repository/app/bundle/version/detail?name=com.springsource.org.aspectj.tools&version=1.5.4&searchType=bundlesBySymbolicName&searchQuery=org.aspectj.tools that exports "org.osgi.framework". Before I put in this logic I would often find the sigil resolver trying to download an 8.4MB bundle to satisfy a resolution that the framework already provides (which would also cascade into lots of other dependencies to satisy aspectj) :s Anyway, my 2 cents...
