Class ExitOnErrorThreadGroup
java.lang.Object
java.lang.ThreadGroup
org.apache.commons.launcher.ExitOnErrorThreadGroup
- All Implemented Interfaces:
- Thread.UncaughtExceptionHandler
public class ExitOnErrorThreadGroup
- extends ThreadGroup
A class that subclasses the ThreadGroup
class. This class is used
by ChildMain.main(String[])
to run the target application. By using
this class, any Error
other than 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
Error
and destroy the thread. However, when an uncaught
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 Thread.Thread(ThreadGroup, String)
or other similar
constructors.
