Christian Schneider commented on KARAF-4547:
--------------------------------------------
The reason is that the resolver in equinox is too old. As equinox does not
closely follow the felix resolver releases and even hand pick changes they
include we can not rely on equinox to fix this. So we embed the resolver code
from a stable felix release into the features.core jar. This makes the karaf
feature service independent from the equinox resolver code.
> Embed resolver in features.core to avoid errors in bundle resolution when
> installing CXF as boot feature

> This bug was originally reported by our Talend ESB team. I have attached the
> link to the issue.
> The issue seems to happen on windows and linux but only on equinox. On felix
> it works fine.
> I assume that this might be releated to the felix resolver. Equinox contains
> an older version of the resolver.
