Revision 1356236

FELIX-3577 Adapt to new helper classes and add dependency to OSGi Core 5.0 (to
  have support for generics). In turn we limit the Framework API import to 1.4
  (aka R4.1) to still be able to support older framework releases (the integration
  tests run with Felix Framework 1.8.0). This also allows me to remove the copy
  of the generified OSGi ServiceReference class.
