DrasylSchedulerUtil (drasyl: General-Purpose Overlay Network Framework - Core Package 0.4.1 API)

java.lang.Object
- org.drasyl.util.scheduler.DrasylSchedulerUtil

```
public final class DrasylSchedulerUtil
extends Object
```
It is an intentional behavior that this scheduler ensures that the JVM is not automatically terminated once all sequential program flows have been processed. A corePoolSize of 0 would prevent this behavior, but would also have a negative effect on performance. The ThreadPool would not start to create a new thread to process until the workQueue limit is reached. Assuming that the workQueue limit is never reached, the schedule would never start processing the already submitted tasks.
