java.lang.NoClassDefFoundError: java.lang.NoClassDefFoundError: org/jgrapht/ext/JGraphXAdapter

The problem here is that the various JGraphX bundles need some wiring that they don't have. It's complicated because both bundles include Java classes in the org.jgrapht.ext package.

At one point I thought of trying to register some explicit dependencies but this didn't work because the mvn deployer (unlike the wrap deployer) won't allow us to modify / synthesize the metadata for abundle at deploy time.
