SimpleAsyncTaskScheduler: consistently apply default error handling

[zyro23]

Affects: 6.1.4 (virtual threads enabled)

---

SimpleAsyncTaskScheduler does apply default error handling (and logging) for:

• schedule(Runnable task, Trigger trigger)
• scheduleWithFixedDelay(Runnable task, Instant startTime, Duration delay)
• scheduleWithFixedDelay(Runnable task, Duration delay)

but does not apply it for:

• schedule(Runnable task, Instant startTime)
• scheduleAtFixedRate(Runnable task, Instant startTime, Duration period)
• scheduleAtFixedRate(Runnable task, Duration period)

i think default error handling (especially logging) should be applied in all cases.

ill reference a repro sample app that uses schedule(Runnable task, Instant startTime).
running the app, you can see corresponding stderr output but no other handling/logging taking place:

2024-02-20T12:46:53.948+01:00  INFO 2924 --- [           main] com.example.demo.DemoApplication         : Started DemoApplication in 0.605 seconds (process running for 0.99)

thanks & regards.
