After some trial and error, mostly with figuring out that I needed to
specify ";singleton:=true" on my Bundle-SymbolicName header in order
to get its bundle's plugin.xml file read, I got my application
registered and fired up by the framework.

However, I'm now puzzle by RegistrationStrategyOSGI's method
createExecutableExtension(), which insists on being able to
default-construct my application class. If my application class can't
take any constructor arguments, how is it going to get ahold of a

I looked at the IApplicationContext interface provided to the start()
method, expecting to find it there, but the only Bundle exposed there
is the "branding bundle".

  Spring OSGi once all its dependent services were available.
