As I explained, I don't think that's possible. The Main class is only responsible for shutting the framework when using the bin/stop script and it does not have anything to do when shutting down the framework from the inside using osgi:shutdown (or anything calling stop on the system bundle). Another way to ensure that the listener will be called first would be to give to its bundle a very low start level so that it's listener will be registered first.
