public interface AsyncTaskExecutor extends TaskExecutor
TaskExecutor implementations,
offering support for Callable.
Note: The Executors class includes a set of
methods that can convert some other common closure-like objects, for example,
PrivilegedAction to Callable before executing them.
Implementing this interface also indicates that the TaskExecutor.execute(Runnable)
method will not execute its Runnable in the caller's thread but rather
asynchronously in some other thread.

task.task - the Runnable to execute (never null)startTimeout - the time duration (milliseconds) within which the task is
supposed to start. This is intended as a hint to the executor, allowing for
preferred handling of immediate tasks. Typical values are TIMEOUT_IMMEDIATE
or TIMEOUT_INDEFINITE (the default as used by TaskExecutor.execute(Runnable)).TaskTimeoutException - in case of the task being rejected because
of the timeout (i.e. it cannot be started in time)TaskRejectedException - if the given task was not acceptedTaskExecutor.execute(Runnable)Future<?> submit(Runnable task)
