[Java] Interface TaskPreprocessor

@Deprecated
public interface TaskPreprocessor

The preprocessor is an internal mechanism to decorate Tasks. This can be used to enhance tasks that they acquire a synchronized block (to cause them to effectively run singly-threaded), or clear intermediate queued jobs, etc.
