The current implementation of "Resolve Missing References" does not completely implement reference resolution as the name implies. Currently, the only capability for resolving references is to re-add missing references by name into the system which can cause duplications within platforms, libraries, etc... instead of maintaining a clean environment. An example would be having installed the Sun Wireless Toolkit 2.5.2 as WTK-2.5.2 under NetBeans 6.1, then upon installing NetBeans 6.5 and opening the project, having to re-install the currently existing Sun Wireless Toolkit 2.5.2 as WTK-2.5.2 if you follow the "Resolve References" hint dialog that pops up upon opening the project. As lhasik identifies in the referenced issue, the only way to resolve the references using existing installed platforms/libraries/etc... is to go into the Project Properties and replace the old references with the new references. These two separate capabilities for references resolution need to be combined into a single "Resolve Missing References" capability accessed by the user when the "Resolve References" hint dialog is displayed and the user selects to resolve the references. See http://www.netbeans.org/issues/show_bug.cgi?id=140356 for more background details.
