What's puzzling me is why these dependencies are getting handled (or
perhaps ignored) at compile time and bundle build time, then surfacing
at load/update time. I thought embed transitive was supposed to deal
with that at bundle build time.
obr seems tantalizing for load time resolution but I don't see how it
helps with my current problem, finding dependencies of poorly understood
source code. Am I missing something?

You could look into the bundle repository OBR. Its documented on the
felix pages.
You build a repository over all your bundles, and when you use the
bundlerepository bundle in felix to install from the repository it
automatically deploys all the dependencies too.
This means that you have to index your bundles with a tool called
BIndex, or use maven-bundle-plugin to build your bundles.
take a look at
http://felix.apache.org/site/apache-felix-osgi-bundle-repository.html
http://felix.apache.org/site/apache-felix-maven-bundle-plugin-bnd.html
http://www.osgi.org/Repository/BIndex
It can take a while to get it working flawlessly, but once it runs it's
smooth.

What's the right way to chase dependencies?
One of my components is an OpenSSO policy enforcement point that
originated with source code from a Netbeans tutorial. It has
dependencies to god know what. I can work the OpenSSO issues. What I
need help with is how experts deal with similar problems. I don't want
to rework that until I get what I have now to load.
This shows where I'm at and how I've been dealing with it. My current
goal (unless someone can show a better way) is for the core and each
component to fully (transitively) enclose all of its dependencies.
That makes for big jars and slow compiles but that's the mental model
I'm working; that a component should contain everything it needs (with
obvious exceptions for java.*, soakit.core.*, etc).
I'm new to this and don't understand whether other models exist that
might work, for example tracking down dependencies at load time (seems
that violates the goal to me but whatta I know; I'm the newbie).

Each try takes about 30 minutes right now, and there's no sign this
chase is near ended. Surely there's a better way. Please share it.
