Hello I found strange code. Is it needed or may be deleted?
org.netbeans.upgrade.AutoUpgrade // the order of VERSION_TO_CHECK here defines the precedence of imports // the first one will be choosen for import private static final List<String> VERSION_TO_CHECK = Arrays.asList ( ".netbeans/7.1.2", ".netbeans/7.1.1", ".netbeans/7.1", ".netbeans/7.0", ".netbeans/6.9" );//NOI18N // userdir on OS specific root of userdir (see issue 196075) static final List<String> PRE_APACHE_NEWER_VERSION_TO_CHECK = Arrays.asList ("8.2", "8.1", "8.0.2", "8.0.1", "8.0", "7.4", "7.3.1", "7.3", "7.2.1", "7.2"); //NOI18N // XXX: copy to autoupgrade.pluginimporter and org.netbeans.modules.autoupdate.pluginimporter.Installer similar versions variables private static final List<String> VERSION_TO_CHECK = Arrays.asList (".netbeans/7.1.2", ".netbeans/7.1.1", ".netbeans/7.1", ".netbeans/7.0", ".netbeans/6.9"); //NOI18N private static final List<String> PRE_APACHE_NEWER_VERSION_TO_CHECK = Arrays.asList ("8.2", "8.1", "8.0.2", "8.0.1", "8.0", "7.4", "7.3.1", "7.3", "7.2.1", "7.2"); //NOI18N
