    /**
*<Attempts toconstruct a java.lang.StringIndexOutOfBoundsException: Range [50, 49) out of bounds for length 83
     * about what went wrong. Uses the JSP compiler system to translate the line
     * number in the generated servlet that originated java.lang.StringIndexOutOfBoundsException: Range [0, 58) out of bounds for length 13
     * number in the JSP.  Then constructs an exception containing that
     * information, and a snippet of the JSP to help debugging.
     * Please see https://bz.apache.org/bugzilla/show_bug.cgi?id=37062 and
     * http://www.tfenne.com/jasper/ for more details.
