NoSuchMethodError is thrown during creation of an instance of XPathException. This
error is thrown when jaxp-1.3-beta-b14 build 12_apr_2004 is used with jdk1.3.1.

The sample is provided below; it fails on JDK 1.3.1.
------------------------------------test.java-----------------------------
import javax.xml.xpath.XPathException;

public class test {

    public static void main(String [] args) {
        XPathException exc = new XPathException(new Exception("q"));
        System.out.println("OK");
    }
}

The constructor XPathException(Throwable) throws NoSuchMethodError because it calls
the superclass constructor Exception(Throwable) and in jdk1.3.1 the Exception class
does not have the constructor Exception(Throwable). It looks like that JAXP 1.3
classes are built by the jdk1.4 compiler. Note that the sample provided is compiled
successfully on jdk1.3 with jaxp-1.3-beta-b18-09_jun_2004.

So this JAXP 1.3 constructor of XPathException can not be used on jdk1.3 as it uses
API from jdk1.4
