  +--java.lang.isolate.IsolateEvent.ExitReason

Enclosing class:

IsolateEvent

public class IsolateEvent.ExitReason

extends Object

Provides information about how an isolate became terminated. It indicates the "reason" the isolate died.

The last valid termination cause determines the reason code. For example, if an isolate exits implicitly (IMPLICIT_EXIT), but a remote isolate issues a halt during the execution of shutdown hooks, the OTHER_HALT code will be provided as the reason.

IsolateEvent.getExitReason()

UNCAUGHT_EXCEPT

public static final int UNCAUGHT_EXCEPT

The last non-daemon thread exited due to an uncaught exception.

If a daemon thread dies with an uncaught exception, that will not cause the containing isolate to die. Additionally, only if the last non-daemon thread dies with an uncaught exception will this reason be noted. Uncaught exceptions in shutdown hooks do not count, either.
