package which is based on Java 5's java.util.concurrent.ExecutorService
@Deprecated public class TimerTaskExecutor
TaskExecutor implementation that uses a
single Timer for executing all tasks, effectively resulting in
serialized asynchronous execution on a single thread.

Note that calls to execute(Runnable, long) will use the
given timeout as delay if it is lower than the general delay.

Timer instance. Called by afterPropertiesSet
if no Timer has been specified explicitly.
The default implementation creates a plain non-daemon Timer.
If overridden, subclasses must take care to ensure that a non-null
Timer is returned from the execution of this method.
