Method Detail

run

public void run()

The monitor thread loops until the pool is shutdown. It waits for tasks with completion timeouts and sleeps until the next completion timeout and then interrupts the associated task thread, and invokes stopTask on the TaskWrapper. A new timeout check is then inserted with a 1 second timeout to validate that the TaskWrapper has exited the run method. If it has not, then the associated task thread is stopped using the deprecated Thread.stop method since this is the only way to abort a thread that is in spin loop for example.
