Description

I am using the resolver as a "multi-root" resolver in order to resolve all my resources in one pass. This may cause org.apache.felix.resolver.ResolverImpl.calculatePackageSpaces to be called multiple multiple times for the same resource if it is required by multiple resources in the set of resources that is being resolved. This causes an artificial explosion of blame candidates when trying to determine a consistent class space solution. Ultimately this leads to a very long resolution process or worse case an out of memory error.
