Comment 1 Allan Zhang CLA 2010-11-02 16:13:38 EDT 
It appears the exception is intentionally logged from (above) at org.eclipse.jpt.core.JptCorePlugin.projectHasPluginNature(JptCorePlugin.java:313)

    public static boolean projectHasPluginNature(IProject project) {
        try {
            return project.hasNature("org.eclipse.pde.PluginNature");
        }
        catch (CoreException ce) {
            // fall through
            log(ce); <---------------------------------------------------------------------------------
        }
        return false;
    }

The method returns false without any problem.
