Same "karb5.conf" file successfully getting parsed in Java 6.
Exception is due to following method which newly added in Java 7
800 private static String More ...trimmed(String s) {
801 s = s.trim();
802 if (s.charAt(0) == '"' && s.charAt(s.length()-1) == '"' ||
803 s.charAt(0) == '\'' && s.charAt(s.length()-1) == '\'') {
804 s = s.substring(1, s.length()-1).trim();
805 }
806 return s;
807 }
REGRESSION. Last worked in version 6u45
