* registry (and its listeners) of the new contributions. Problem is : some bundles listen to new
* contributions, but ignore the event of contribution removals (when we uninstall the bundle). We
* would thus end with "invalid registry object" exceptions thrown ... with no way to prevent or
* fix them whatsoever. Equinox does not provide us with an API to disable the contributions from
* the bundle we're installing, temporarily disable the extension listeners... or any other way to
* workaround this registry issue. We'll then make use of the fact that the EclipseBundleListener
* does not add contributions from a contributor which has already been added: we'll add the
* contributor beforehand with an empty plugin.xml, disabling all potential contributions this
* bundle would have made otherwise.
