> This is similar to FELIX-4727. There are several issues with how namespace
> is handled in getCapabilities and getRequirements for the
> org.apache.felix.resolver.WrappedResource class
> In getCapabilities the namespace is correctly used to ask the host and
> fragment resources for the named capabilities. But then that list is saved
> into the m_cachedCapabilities field. If you first ask for the 'foo'
> namespace it will save all the 'foo' capabilities to m_cachedCapabilities,
> then if you ask for the 'bar' capabilities it will simply return the
> m_cachedCapabilities from before with 'foo' capabilities.
> In getRequirements the namespace is completely ignored. I think there are
> several reasons to stop lazily crating these caches. It leads to strange
> bugs like the ones above, but also there is no synchronization here and the
> var is not volatile so I think there could be some issues with
> multi-threading. Now that the resolver is multi-threaded I think we should
> stop creating these lists of capabilities and requirements lazily. Instead I
> think we should make them final and create them in the constructor.
