18. 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

19. 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?

20. P2 vs OBR vs Nimble
• IMHO
• OBR is simplistic
• P2 is complex and optimised too early
• Nimble is new
