Hello
Last week we found that our james 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 whith
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:"+ teste );
}
}
you can create a file named badmsg.txt with the following attached test
message
Any idea how to solve this
