Hello guys,
I asked at equinox-dev and it seems there's no Bundle-BuddyPolicy header
in OSGi standard
(my question listed in [1] and).

Moreover there's nothing wrong with Eclipse-BuddyPolicy (except it's
Eclipse-specific). It should be deprecated - at least as far as I know.

Whether it's good idea to include this Equinox specific header is
different question. My personal state is to include it because
* other OSGi frameworks will ignore this header
* for Equinox OSGi it doesn't mean any significant load
* users wishing to go "buddy classloading policy" way will not have to
edit manually unpack JAR, modify MANIFEST.MF headers and pack it as JAR

Have a nice day!

     Hi Gunnar, Ekke,

     FYI, since a few days, we started publishing a composite p2 repository
     at http://logback.qos.ch/p2/. It contains two child repositories,
     called "proper" and "beagle". The "beagle" repo publishes the
     logback-beagle plugin which is a console-like view for logging. The
     "proper" repository publishes bundles for slf4j-api, logback-core and

     OSGi bundles still need a way to pass logback-classic a configuration
     file. Several technical for achieving this are explained by Libor
     Jelinek at [1]. I think logback-classic should support Eclipse buddy
     policy. Would you have any objections if I added
     "Eclipse-BuddyPolicy: registered" to logback-classic.jar's MANIFEST ?

     Your comments are most welcome,
