J11_3_2_Exceptions.java
=================================================================

class J11_3_2_Exceptions {


 public static void main(String[] args) {

oMyThread1.stop(); //Put a breakpoint here, and stepover
//put another breakpoint at the catch(ThreadDeath) handler
//The "future" execution point will be the catch(ThreadDeath) handler
//Note: the catch handler may NOT be the immediate next step

//An asynchronous exception is,
//by contrast, an exception that can
//potentially occur at any point in
//the execution of a Java program.
//Asynchronous exceptions are rare in Java. They occur only as a result of:
//· An invocation of the stop methods of class Thread ( §20.20.15, §20.20.16) or ThreadGroup ( §20.21.8, §20.21.9)
//· An InternalError (§11.5.2.2) in the Java Virtual Machine

class TestJ11_3_2_MyThread extends Thread {

public void run() {
try {
for(;;) System.out.println("Forever...");
}
catch (ThreadDeath e ) { //Consults 20.20.15 for detail
System.out.println("catch in Thread run()..."); // TC0001.1
throw e; //Consults 20.20.15 for detail
}
