> If uninstalling a bundle in the BundleActivator#start() method like in the small snipplet below, and the container is in his starting phase the container will never leave this state. In this state its not possible to start any bundle or to shutdown the container with the gogo shell. The pretty same issue occurs if the bundle is cached and it uninstalls a also cached bundle. 
> To reproduce:
> 1) Download current Felix 4.0.2 distribution.
> 2) create two bundles, 
>    a) one with the Activator below.
>    b) one with the symbolicname "usual.bundle.usual.bundle".
> 4) put them into e.g. the "extra_bundles" folder
> 5) add
> felix.auto.start.1=file:extra_bundles/test-0.0.1-SNAPSHOT.jar \
> file:extra_bundles/usual.bundle-0.0.1-SNAPSHOT.jar
> to the config.properties
> 6) execute java -jar bin/felix.jar
> You will see
> C:\Users\...\Desktop\felix-framework-4.0.2>java -jar bin/felix.jar
> uninstalling bundle: usual.bundle.usual.bundle [7]
