java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

This also happens with JDK 1.3.1, 1.4.0-beta-b65.

VM crashes when running multi threaded application if a run method throws an
exception in a finally block.

A sample program that shows the problem follows:

package untitled30;

public class Application1 {
    boolean packFrame = false;

    /**Construct the application*/
    public Application1() {
    }
        
    void testThread(int size) {
        int i=0;
        while (i < size) {
            TT tt = new TT();
            tt.setLoop(i * 11);
            tt.start();
            i++;
        }
    }
    
    
    /**Main method*/
    public static void main(String[] args) {
        Application1 ap = new Application1();
        
        ap.testThread(100);
    }
    
    
    class TT extends Thread {
    
    
            int loop=0;
            
            public void setLoop(int l) {
                loop = l;
            }
            
            public void run() {
                int j =0;
                try {
                    while (j < loop) {
                        if (j % 50 == 0)
                            System.out.println("I am " + this + " " + j);
                        j++;
                    }

                } catch (Exception e) {
                
} finally {
System.out.println (" i die " + this);
// the following throw can cause the VM to crash
                    try {
                        throw new Exception("Stack Cleanup");
                    } catch (Exception e) {
                    // Clean!
                    }
}
            }
    }
}
