@FunctionalInterface public interface TaskDecorator
Runnable
 about to be executed.
 Note that such a decorator is not necessarily being applied to the
 user-supplied Runnable/Callable but rather to the actual
 execution callback (which may be a wrapper around the user-supplied task).
 
The primary use case is to set some execution context around the task's invocation, or to provide some monitoring/statistics for task execution.
NOTE: Exception handling in TaskDecorator implementations
 may be limited. Specifically in case of a Future-based operation,
 the exposed Runnable will be a wrapper which does not propagate
 any exceptions from its run method.
