Chapter 17. Asynchronous Transfer of Control

• Thread Interrupt in Context

• Asynchronous Interrupt Firing

• Rules for Async Exception Propagation

• Noninterruptible Code

• Use of ATC for Thread Termination

Asynchronous transfer of control (ATC) is a mechanism (broadly similar to Thread.stop) that lets one thread throw an exception into another thread. ATC is important for some classes of real-time applications. The RTSJ defines a class, called AsynchronouslyInterruptedException (AIE), for asynchronous exceptions, with special rules that make the exceptions safe for use with the Java programming language:

1. The target thread will not service an asynchronously interrupted exception until it reaches a method that explicitly throws AsynchronouslyInterruptedException ...
