My Thoughts

Spec First?

• OSGi Alliance typically tries to set up standards for vendors to interoperate

• Lots of complexity in development tooling space

• Likely need some consolidation in tools before any agreed specs can be achieved - too many cooks

OSGi vs Jigsaw

• Jigsaw is trying to modularise the JVM in a simplistic manner and maintain backwards compatability

• Module public (default) - ok for past, broken for future

• Class scope vs package scope - resolution hell

• Issue of non java resources?

P2 vs OBR vs Nimble

• IMHO

• OBR is simplistic

• P2 is complex and optimised too early

• Nimble is new
