[jdom-interest] bug in Element?

[Nick Wormley]

Hello -- 

Using the latest revision of Element.java (1.79), 
I get the following stack trace:

Exception in thread "main" java.lang.NullPointerException
        at org.jdom.Element.setMixedContent(Compiled Code)
        at org.jdom.Element.setChildren(Element.java:1009)
        at Test.main(Test.java:14)

by runnning this code:


import java.util.*;
import org.jdom.Element;

public class Test {

    static public void main( String[] args ) {
	
	List list = new ArrayList();
	list.add( new Element( "foo" ) );
	
	new Element( "bar" ).setChildren( list );
    }
    
}


It looks like there should be a null check on oldContent at 
line 919, since it is possible that the Element had no 
content prior to the setChildren call.


Nick.
