Class ExitOnErrorThreadGroup
public
class
ExitOnErrorThreadGroup
extends ThreadGroup
A class that subclasses the {@link ThreadGroup} class. This class is used
by {@link ChildMain#main(String[])} to run the target application. By using
this class, any {@link Error} other than {@link ThreadDeath} thrown by
threads created by the target application will be caught the process
terminated. By default, the JVM will only print a stack trace of the
{@link Error} and destroy the thread. However, when an uncaught
{@link Error} occurs, it normally means that the JVM has encountered a
severe problem. Hence, an orderly shutdown is a reasonable approach.
Note: not all threads created by the target application are guaranteed to
use this class. Target application's may bypass this class by creating a
thread using the {@link Thread#Thread(ThreadGroup, String)} or other similar
constructors.
