Thomas Diesler commented on JBOSGI-457:
---------------------------------------

This requires an update of the resolver. All collections need to be reviewed for their concurrency policy.

{code}
        for (XCapability cap : resModule.getCapabilities()) {
            Set<XRequirement> wiredReqs = cap.getWiredRequirements();
            for (XRequirement req : wiredReqs) {
                Bundle bundle = req.getModule().getAttachment(Bundle.class);
                AbstractBundleState importer = AbstractBundleState.assertBundleState(bundle);
                if (importer.getState() != Bundle.UNINSTALLED)
                    return true;
            }
        }
{code}
