@WebListener
public class BackgroundJobManager implements ServletContextListener {
Scheduler not runs after MyTask throws Exception. How to run the Scheduler continuously even though SomeTask() throws Exception.

why do you still want to run thread even after exception? Generally, exception is a situation where program doesn't perform expected operation.

Not all exceptions are fatal. Often, an error condition may be recoverable at a later point of time or may be localized one.
If a thread has the task of processing a thousands of files coming in, and file #453 has some encoding error, it doesn't warrant stopping all processing of every other subsequent file.

Kri Shan, inside your task, catch exceptions, log them somewhere at a minimum, and for recoverable errors, either retry immediately a limited number of times or consider resubmitting the task to executor for processing later on.

Use a loop and resubmit it the same way you submitted it the first time.
