> The InternetHeaders getMatchingHeaders(), getNonMatchingHeaders(), etc. methods give an NPE if a null match list is provided.  The Sun implementation treats this the same as an empty array.  The following simple program can demonstrate the problem:  
> import javax.mail.internet.InternetHeaders; 
> import javax.mail.Header; 
> import java.util.Enumeration; 
> public class TestMatchHeaders  
> {
>     static public void main(String [] args) {
>         InternetHeaders headers = new InternetHeaders(); 
>         headers.setHeader("Subject", "Hello"); 
>         headers.setHeader("From", "Me"); 
>         
>         Enumeration e = headers.getMatchingHeaderLines(null); 
>         
>         System.out.println(">>>>> Matching lines"); 
>         
>         while (e.hasMoreElements()) {
>             System.out.println((String)e.nextElement()); 
>         }
>         
>         e = headers.getNonMatchingHeaderLines(null); 
>         
>         System.out.println(">>>>> Non-Matching lines"); 
>         
>         while (e.hasMoreElements()) {
>             System.out.println((String)e.nextElement()); 
>         }
>         
>     }
> }
