[xsl] XALAN: exceptions from extension functions

Subject: [xsl] XALAN: exceptions from extension functions

We're using extension functions in Xalan 1.2.2.  We've noticed that
exceptions that are thrown within extension functions are lost.  Looking
into the code I notice that it happily eats the exception, in fact has a
commented out XPathException.  Is there any reason for this?  Some
standards thing where it isn't cool to throw an exception from an
extension function?

The relevant code.....
        return callJava(javaObject, funcName, argArray, methodKey);
        return e.call (null, funcName, argArray);
    catch (Exception e) 
      // throw new XPathException ("Error with extension in
callFunction.", e);
      String msg = e.getMessage();
      if(null != msg)
        if(msg.startsWith("Stopping after fatal error:"))
          msg = msg.substring("Stopping after fatal error:".length());
        System.out.println("Call to extension function failed: "+msg);
        throw new XPathProcessorException ("Extension not found");
