Is w.r.t. to utilizing Jersey without specific support in GF v3
prelude? for example i understand that GF has support for META-INF/
services.
We realize we have to do some more work to improve on the OSGi
integration. For example currently for GF we rely on the jersey-
bundle.jar and IIRC pretty much every package is exported. The reason
being is that although Jersey was split into several maven modules the
package boundaries between them were not cleanly defined. This has
been fixed now so that modules only depend on API/SPI packages of
other modules and there is no package names shared between modules.
For the 1.0.2 release we hope to add proper OSGI information to each
module.
If there is any overlap between what you have done and what we would
like to do perhaps we can share the details on what additional work
you needed to do?

The context class loader is used consistently throughout Jersey to
dynamically load classes: stuff from META-INF/services and classes
from names when class scanning for root resource and provider classes.

And the RuntimeDelegationImpl will be in another bundle?

Hmm... i must admit to not being an expert in the class loading
esoteric nature of the JVM and how OSGi works in this respect. So it
is hard for me to know what problems, if any, this might induce. What
types of problem might you expect? What should i be looking for?
Thanks,
Paul.
