Interface for handlers invoked when a Thread abruptly
terminates due to an uncaught exception.
When a thread is about to terminate due to an uncaught exception
the Java Virtual Machine will query the thread for its
UncaughtExceptionHandler using
getUncaughtExceptionHandler() and will invoke the handler's
uncaughtException method, passing the thread and the
exception as arguments.
If a thread has not had its UncaughtExceptionHandler
explicitly set, then its ThreadGroup object acts as its
UncaughtExceptionHandler. If the ThreadGroup object
has no
special requirements for dealing with the exception, it can forward
the invocation to the default uncaught exception handler .
