Iiro Nykänen updated NETBEANS-1774:
-----------------------------------
Description:
We are using a library with fragmented OSGi bundles in our NetBeans Platform
application. The bundles resolve fine, but during runtime the NetigsoLoader
instance that was created for the bundle tries to load classes from the
fragment, instead of the host. This is not desirable, and e.g. Felix throws an
exception (see link 1).
The issue is in Netigso, in the createLoader method, which doesn't handle the
caught BundleException correctly (thrown when trying to start the fragment, see
link 2).
I have fixed this for our application by simply looking up the fragments host
bundle and substituting the fragment with its host in the created NetigsoLoader.

I'm not sure how your process goes, but I can drop a pull request of my fix if
you want.
