Since the parameters `-Djdk.virtualThreadScheduler.parallelism=N` , `-Djdk.virtualThreadScheduler.maxPoolSize=M`, `-Djdk.virtualThreadScheduler.minimumRunnable=Y` have already been made available, it would be worth considering opening up additional ForkJoinPool-related parameters: `-Djdk.virtualThreadScheduler.corePoolSize=X`, `-Djdk.virtualThreadScheduler.keepAliveTime=Z` and `-Djdk.virtualThreadScheduler.timeUnit=S`.

In particular, configuring corePoolSize can help reduce jitter caused by thread ramp-up during application startup, while keepAliveTime and timeUnit ensures more threads are available within the time expected by users. Opening these parameters would be highly meaningful for optimizing virtual thread scheduling.

I look forward to your advice and feedback！Thank you.
