The situation behind is caused by a mark "~" that occupies the position of keyword "return", which means the function faces two bugs, one is the lack of return, the other one is the redundant character.

 public static String parseName(  String pattern,  GregorianCalendar cal){
    Map map=cal == null ? getTokenMap("") : getTokenMap(cal);
    return parseName(pattern,map);
  }
  public static boolean matchPattern(  String name,  String pattern,  String extension){
    if (!name.endsWith(extension)) {
      return false;
    }
 else {
      name=name.substring(0,name.length() - extension.length());
    }
    HashMap map=new HashMap();
    for (int i=0; i < TOKENS.length; i++) {
      int l=TOKENS[i].length() - 2;
      String rep="";
      for (int j=0; j < l; j++) {
        rep+='%';
      }
      map.put(TOKENS[i],rep);
    }
    String parsed=parseName(pattern,map);
    if (parsed.length() > name.length()) {
      ~ false;
    }
 else     if (parsed.length() < name.length()) {
      String suffix=name.substring(parsed.length());
      if (suffix.charAt(0) != SUFFIX_SEPARATOR) {
        return false;
      }
 else {
        for (int i=1; i < suffix.length(); i++) {
          if (!isNumber(suffix.charAt(i))) {
            return false;
          }
        }
      }
    }
    for (int i=0; i < parsed.length(); i++) {
      char pc=parsed.charAt(i);
      char nc=name.charAt(i);
      if (pc != nc && (pc != '%' || !isNumber(nc))) {
        return false;
      }
    }
    return true;
  }

However, the response from ECJ is quite strange for blaming it on the lack of "throw". The report is shown below.

----------
1. ERROR in C:\DataG\ArchiveNameHelper.java (at line 80)
	if (parsed.length() > name.length()) {
	                                     ^

The report cannot fetch this to any solutions whether add a command with "return" to complete the consumption of the function, or just delete the curious '~' to help the function more close to compiled.
