May be better to avoid potetially superfluous lookup of UTF-8:

public static Charset defaultUnicodeCharset() {
     if (defaultUnicodeCharset == null) {
         synchronized (Charset.class) {
             String csn = AccessController.doPrivileged(
                     new GetPropertyAction("file.encoding.unicode"));  // indent 8 spaces !!
             if (csn == null || (defaultUnicodeCharset =lookup(csn)  == null)) {
                 defaultUnicodeCharset = forName("UTF-8");
             }
         }
     }
     return defaultUnicodeCharset;
}
