Message that locks java

Question

Hello
Last week we found that our smtp (James java server) was using a lot of CPU
after several days trying to identify the problem we found a japanese message that was causing the problem. We have a custom mailet that includes a SPAM string in the subject of the message, whem
we try to do that in this message the thread starts eating all the CPU
and locks the problem occours whem I try to get the subject line with
getSubject()
I have created a little program that simulates the problem
import javax.mail.internet.MimeMessage;
import java.io.*;
import javax.mail.*;
import javax.*;
import javax.mail.internet.*;
import javax.activation.*;
import java.util.Properties;
import java.util.Date;
class ts { 
public static void main (String[] args) throws Exception {   
Properties properties = System.getProperties();
Session session = Session.getInstance(properties, null);
FileInputStream fis = new FileInputStream("badmsg.txt");
MimeMessage c = new MimeMessage(session, fis);
System.out.println("Hello");
String teste = c.getSubject();
System.out.println("MSG:"+ test );
you can create a file named badmsg.txt with the following test message
Subject: [Weekly Mag2 2004/01/28 =?ISO-2022-JP?B?GyRCJWElLCVNISYbKEI=?=
        =?ISO-2022-JP?B?GyRAGyRCJTMlcyU/JS8lSCQsSVRNVyRLISkyd0UsQDgzaCRPJDkbKEI=?=
        =?ISO-2022-JP?B?GyRAGyRCJDAkPSQzISobKEI=?=]
Test

I found I way to solve this problem
instead of using getSubject I use getHeader(�subject�,null)
