      Description

      In org.apache.solr.analysis HTMLStripCharFilter use a wrong isHex()-method that return characters like 'X', 'Y' as valid hex chars:

        private boolean isHex(int ch) {
          return (ch>='0' && ch<='9') ||
                 (ch>='A' && ch<='Z') ||
                 (ch>='a' && ch<='z');
        }
      

      If only characters from [0-9a-zA-Z] are allowed, the readNumericEntity method will detect faster a mismatch.
