isEclipseNLS
private boolean isEclipseNLSEclipse uses reflection to initialize NLS message bundles. Classes which using this mechanism are usually extending org.eclipse.osgi.util.NLS class and contains lots of public static String fields which are used as message Constants. Unfortunately these fields cannot be final, so FB reports tons of warnings for such Eclipse classes.
