> I have a karaf sample project spanning multiple bundles that get combined into a single KAR. The KAR is then packaged through a karaf-assembly module in a karaf distro.
> The project can be found at: https://github.com/tonyganchev/blog/commit/807ed40c80b597d90ecb955b28ccf613b7e02bfd (pointed to the revision that introduces the issue)
> When setting installAllFeaturesByDefault to false I get the following exception (on 4.0.4-SNAPSHOT in this case, but essentially the same on all 4.0.x versions)
