It's been a while, so I'm not up on the latest Jigsaw details. A while back I was working on building traditional Java (Spring MVC/Spring/Hibernate) web applications using OSGi. At the time, I hit some non-trivial challenges with any library that used a class discovery mechanisms that assumed a flat classpath. Jigsaw is purported to be simpler, so hopefully it's not a big issue, but when our team starts using Java 9, that'll be one of the big risks I'll be looking for.

At the same time, I am excited that many issues with transitive dependency resolution will be easier, and it will be easier to enforce code architecture principles (i.e., not just calling whatever code from whatever place just because it's on the classpath already).
