When a DragSource is created, it causes a hang in windows 98 in build 11. This passes in build 10. java has to be killed by using ctrl+alt+del as a simple ^C does not kill it. Or, the VM has to be self destructed. This can be seen from the testcase given below.

The console output is :
[C:/work/temp] java -showversion -XX:SelfDestructTimer=1 DragSourceBug
java version "1.4.1-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-beta-b11)
Java HotSpot(TM) Client VM (build 1.4.1-beta-b11, mixed mode)
                
Creating Drag Source
Done creating   
VM self-destructed 
[1] + Done(134) java -showversion -XX:SelfDestructTimer=1 DragSourceBug
  0xfff348e9    Abort   java

Steps to reproduce the problem :
1. Compile the source code given.
2. Run the code with build 11.
3. The code does not exit. It has to be explicitly killed or the VM self-destructed.

------------------------------BEGIN SOURCE-------------------------
import java.awt.dnd.*;

public class DragSourceBug {
        public static void main(String [] args){
                System.out.println("Creating Drag Source");
                DragSource ds = new DragSource();
                System.out.println("Done creating");
                ds = null;
        }
} 
------------------------------------END SOURCE---------------------

I am not sure if this problem is related to bug 4683091 which looks similar.
