workaround for Java bug http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6242664
Java 1.5 has a bug where detecting codepoint offsets in strings that are created by String.substring() gives wrong results. The new implementation uses a different method, avoinding the issue. The following code will crash without the fix: final String s = "abcdefg"; final String ss = s.substring(3, 6); final int[] cps = OtpErlangString.stringToCodePoints(ss);
