Yeah, when I was thinking about it, I could think of an "elegant"
solution. Now you have confirmed that. :-)

Currently we do not do anything. I am considering making a framework
extension bundle fragment that adds a bundle classloader that can be used
on J2SE 1.5. The problem I have is that the core Equinox framework is
compiled against the OSGi EE minimum 1.1 library. I could add a bundle
classloader implementation to the core framework that extends the existing
bundle classloader and overrides the getResources method. Then at runtime
pick the correct implementation of the bundle classloader depending on the
level of the EE. But this would force me to compile the core framework
against J2SE 1.5. Something I'm not willing to do at this point. For me
it is probably better to stick this extra class (compiled against J2SE
1.5) in a framework fragment, then runtime can load that version of the
bundle classloader if it is installed and resolved. I would make that
fragment bundle have a required EE of J2SE 1.5 so it could not be
installed on an older VM.

This is probably because the ClassLoader.getResources method is final on
J2SE 1.4 and earlier. In J2SE 1.5 they removed the 'final' from this
method. This makes it impossible to implement a "correct" bundle
classloader on J2SE 1.4 and earlier WRT ClassLoader.getResources. The
implementation of the final ClassLoader.getResources method always
checks
the parent classloader first, there is no way for the OSGi Bundle class
loader to override this behavior. We have the exact same situation in
Equinox.
Ugly.
Tom, so do you have some check in place to do the correct thing when
running on 1.5 as opposed to < 1.5 ? If so, what approach do you use?

bundle.getResources behavior
My understanding of the OSGi spec is that Bundle.getResources() should
only
look in the System classpath if the package name is listed in the
org.osgi.framework.bootdelegation property, is that correct? I am
working
on a problem where Felix is returning a resource from a non-bundle jar
(Felix is embedded) that is on the main application classpath. Any
ideas?
Thanks,
Chris
