      Work Description: liangshuche opened a new pull request #636:
URL: https://github.com/apache/commons-lang/pull/636


   When wrapToken.length() * 2 is larger than str.length(), and str starts with and ends with wrapToken, the function calls str.substring(beginIndex, endIndex) with beginIndex larger than endIndex, which throws a StringIndexOutOfBoundsException.
   
   It should return the original string since it is not quoted properly with the wrapToken according to documentation.
