com.sun.jini.thread.TaskManager

A task manager manages a single queue of tasks, and some number of worker threads. New tasks are added to the tail of the queue. Each thread loops, taking a task from the queue and running it. Each thread looks for a task by starting at the head of the queue and taking the first task (that is not already being worked on) that is not required to run after any of the tasks that precede it in the queue (including tasks that are currently being worked on).

This class uses the {@link Logger} namedcom.sun.jini.thread.TaskManager to log information at the following logging levels:

**`com.sun.jini.thread.TaskManager`**
Level	Description
{@link Level#SEVERE SEVERE}	failure to create a worker thread when no other worker threads exist
{@link Level#WARNING WARNING}	exceptions thrown by {@link TaskManager.Task} methods, and failureto create a worker thread when other worker threads exist
