            // but if many projects are imported, the resource deltas are processed early,
            // and then JDT creates ExternalPackageFragmentRoot instances for which linkedFolder.getLocation() is null,
            // which causes null pointer exceptions in that class' hashCode method, this.externalPath.hashCode(),
            // which completely screws up PDEs own notification handling
            // causing it to handle the same deltas more the once, making a mess of the PDE's model.
            // JDT doesn't create the links until the AutoBuildJob runs, which happens very late in the overall processing cycle.
