Karl Pauls resolved FELIX-463.
------------------------------
Resolution: Invalid
No. It doesn't work like this. You still need to make the packages your bundles
explicitly import available form the system bundle (i.e., add them to the
system.packages property). The bootdelegation is needed only for the case where
you want to make packages available to bundles _without_ them needing to import
them. However, if they import them then it doesn't work. In other words, this
is not a bug in Felix but you will have to adjust your assumptions.
What happens in your case is that the bootdelegation=* effectively short-cuts
the whole resolving process and makes Felix use the bootclassloader _all_ the
time. That one, however, doesn't know about classes that come from a bundle --
hence, the CNFE. Do try to avoid using the bootdelegation feature unless your
really need it - it's not a convenience feature but a last resort.

> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: 1.0.0
> Environment: JDK 1.5.0_06 or 1.6 on Solaris 10/x86
> Reporter: Sahoo
> Priority: Critical
>
> I am having trouble starting Felix when I use
> -Dorg.osgi.framework.bootdelegation="*". When I run using the following
> command:
> '/usr/bin/java -Dorg.osgi.framework.bootdelegation="*" -jar bin/felix.jar',
> it fails like this:
> WARNING: *** Class 'org.apache.felix.shell.impl.Activator' was not found.
> Bundle 1 does not import package 'org.apache.felix.shell.impl', nor is the
> package exported by any other bundle or available from the system class

> Section #3.8.4, Overall Search Order, of OSGi Service Platform Release 4 spec
> does not clearly (or I don't understand it well enough) state what should be
> the behavior. Relevant portions of the spec is given below:
> /1 If the class or resource is in a java.* package, the request is delegated
> to the parent class loader; otherwise, the search continues with the next
> step. If the request is delegated to the parent class loader and the class or
> resource is not found, then the search terminates and the request fails.
> 2 If the class or resource is from a package included in the boot delegation
> list (org.osgi.framework.bootdelegation), then the request is delegated to
> the parent class loader. If the class or resource is found there, the search
> ends.
> /
> Unlike point #1 above, point #2 does not mandate the search to terminate. I
> can understand the search terminating for java.* packages, but why for other
> packages? It seems Felix is terminating the search, therefore I am seeing
> this failure. Can anyone please clarify this? I am using "*, " because I want
> to see how I can make packages from some library jars available to bundles
> without having to set org.osgi.framework.system.packages property?
> I am hoping that if I add my library jars in system classpath and set
> bootdelegation="*", the library jar's content will be automatically available
> to other bundles even if I don't set org.osgi.framework.system.packages
> property. Is this not going to work?
> Thanks,
> Sahoo
