However, Code Recommenders [2] properly declares these uses constraints and has not seen a major problem since we introduced this in 2013(!). Yes, if consumers of the org.eclipse.recommenders.models API also want to use Guava for other purpose, then they are restricted in their choice of Guava versions by what org.eclipse.recommenders.models uses but that's how OSGi works. This is IMHO a small price to pay for generally being able to have two versions of the same bundle in your runtime. No more "one classpath to rule them all", which *might* work in the closely coordinated simultaneous release (although based on [3] I doubt it), but certainly not once third-party plug-ins come into play.
