It seems to be happening because the ResolverImpl.isCompatible() method is comparing two capabilities; one is an AbstractBundleCapability and the other is a WrappedCapability that contains the same instance of AbstractBundleCapability. The result of the comparison is false.
As a quick hack I changed the equals method of WrappedCapability to
{noformat}
@Override
public boolean equals(Object obj)
{
return m_cap.equals(obj);
}
{noformat}
and that seemed to make it work and resolution was successful.
