Richard S. Hall commented on FELIX-467:
---------------------------------------
For what its worth, Tom Watson says Equinox works like this:
-----
Here is what we do in Equinox.
1) First of all, we do not do anything tricky for 1.4 vs 1.5. We assume
ClassLoader.getResources is final and always delegates to the boot class loader
for every package.
2) For Bundle.getResources() we do not actually ask the
ClassLoader.getResources. Instead we wire directly into the proper OSGi
delegation model. This unfortunately means Bundle.getResources() and
ClassLoader.getResources could potentially return different results depending
on what was available from the boot class loader.
Lets ignore that little issue and assume we can override
ClassLoader.getResources and do proper OSGi delegation. The process should look
something like this:
1) Check to see if the resource is in the java/* namespace. If so *only*
delegate to boot and return the Enumeration returned from boot.
2) Check to see if the resource is on the o.o.f.bootdelegation list. If so get
the Enumeration from boot and pass the result to the next step.
3) Check to see if the resource is imported (using Import-Package). If so
delegate to the exporter's local (and fragments) classpath and return the
results in a compound Enumeration which includes the results from the previous
step. If not imported then pass the incoming Enumeration to the next step.
4) Check to see if the resource is accessed from a required bundle (using
Require-Bundle). If so delegate to each required bundle's local (and fragments)
classpath which exports the requested resource package and compound the results
with the incoming Enumeration. Pass the results to the next step.
5) Delegate to the local bundle's (and fragments) classpath. Compound the
results with the incoming Enumeration and return the results.
----
This approach is slightly different than ours, but still can lead to a
situation where packages that are boot delegated AND imported can be combined
for resources. It is different than our proposal because it explicitly stops if
the package is imported.

>
> This issue is linked to FELIX-466
> The R4SearchPolicyCore.findResources(String) method just exits early on a
> first hit, and doesn't continue into imported packages.
> It should aggregate the different hits and return all matching resources.
