Our OSGi stuff is best effort - working on OSGi was like sticking needles directly into
the back of my eyeball, not fun. tbh I find OSGi a real PITA. Too many of our dependencies
do not have real OSGi bundles available, so we have to resort to the spring repository -
where the versions almost never match our original target version. Further when it fails
it's almost freaking impossible to determine why it fails.
We use the spring test module, we provide it all the dependencies that you see, and run
the tests. Other than suggesting to look at the spring OSGi test executions, I can't
really offer more help. But it will nearly always boil down to wrong jars or wrong
versions of jars - figuring out which of those are the problem, is not easy. Either it
works, of it doesn't. If it doesn't, there is no simple way to debug why OSGi
doesn't work. Generally I have to take it back to the last version that worked and
keep incrementally changing it until I find out specifically doesn't work, so I can
address it.
You might find it useful to look at the bundle context that spring osgi creates, here is
all the bundles and their versions necessary for the unit tests to run:

good luck :) Please document any helpers you find, and submit as pull requests.

Thanks Mark, but I still am having issues.
I cloned the latest droolsjbpm-build-distribution and built
drools-osgi-bundles and reviewed the documentation you refenced. I don't see
it stated anywhere, but I assume I need to install and start all of the jars
in drools-osgi-bundles-distribution-5.5.0-SNAPSHOT.zip.
So, I put all of those jars in the AS7's Standalone deployments folder and
started up AS7. The only jar that seemed to have trouble is
*com.springsource.antlr-2.7.6.jar* because of an *IllegalArgumentException:
A fragment is not a module*.
Now I tried to deploy the *knowledge-api-5.5.0-SNAPSHOT.jar*, and I get an
error with *com.springsource.com.sun.tools.xjc:2.1.7* (see stacktrace
below), which prohibits me from installing and starting any of the other
drools bundles mentioned in the doc.
Any thoughts about what's amiss?
