Remarks
Called by the Java Virtual Machine when a thread in this thread group stops because of an uncaught exception, and the thread does not have a specific Thread.UncaughtExceptionHandler installed.
The uncaughtException method of ThreadGroup does the following: <ul> <li>If this thread group has a parent thread group, the uncaughtException method of that parent is called with the same two arguments. <li>Otherwise, this method checks to see if there is a Thread#getDefaultUncaughtExceptionHandler default uncaught exception handler installed, and if so, its uncaughtException method is called with the same two arguments. <li>Otherwise, this method determines if the Throwable argument is an instance of ThreadDeath. If so, nothing special is done. Otherwise, a message containing the thread's name, as returned from the thread's Thread#getName getName method, and a stack backtrace, using the Throwable's Throwable#printStackTrace printStackTrace method, is printed to the System#err standard error stream. </ul>
Applications can override this method in subclasses of ThreadGroup to provide alternative handling of uncaught exceptions.
