An occurrence in a target VM that is of interest to a debugger. Event is the common superinterface for all events (examples include BreakpointEvent, ExceptionEvent, ClassPrepareEvent). When an event occurs, an instance of Event as a component of an EventSet is enqueued in the VirtualMachine's EventQueue.
