[Use Case]: Autostart for Scheduled Asynchronous methods

[njr-11]

As a ...

• Application user/user of the configuration itself
• API user (application developer)
• SPI user (container or runtime developer)
• Specification implementer

I need to be able to ...

arrange for an Asynchronous method to be automatically submitted/scheduled upon application startup

Which enables me to ...

more conveniently code applications that have business logic that should run on a schedule

Additional information

This requirement was discussed in a topic titled "Defining Jakarta EE 12 Scope in Program Plan" on the jakarta.ee-community mailing list.

One way to achieve this might be with a boolean autoStart field,

 @Asynchronous(runAt = @Schedule(daysOfWeek = DayOfWeek.TUESDAY, hours = 1),
               autoStart = true)
 public void weeklyTask() {
     ...
 }

If we wanted, we could also allow it for one-time Asynchronous methods without a Schedule.
