Thanks Neil, So I understand that "framework" means the ClassLoader that loaded the system bundle and not the system bundle Class Loader itself.
That was my initial understanding. But when I tried to delegate our platform packages via bootdelegation and omitting them from system.packages.extra, I got ClassDefNotFound on them. When I added our platform packages to both bootdelegation and system.packages.extra That helped for the platform packages (though I have other problems) That made me think that the "framework" configuration makes bootdelegation delegate to system bundle itself, which in his turn, import them with system.packages.extra and so gets them from the class loader that loaded him. Hope I didn’t confused you.

Bear in mind that that classloader would normally perform parent delegation up the chain, unless you have implemented alternative custom behaviour in any of those classloaders.

Our hosting application (platform) creates several class loaders beneath the jvm system class loader, and from one of them the OSGi FW is created. Class loader hierarchy something like: jvm boot -> jvm ext -> jvm system -> custom1 -> custom2 -> custom3 -> OSGi FW (aka system bundle) We now experience problems with our platform Profiler. How can I make the bootdelegation to delegate to the class loader that loaded the OSGi FW? org.osgi.framework.bundle.parent = ??? to my understanding, setting "app" will delegate to the jvm system class loader. setting "framework" will delegate to the system bundle.
