java.util.concurrent.ScheduledThreadPoolExecutor’s pool is sized with `corePoolSize, so setting corePoolSize to zero means the executor will have no threads and run nothing.

This rule detects instances where corePoolSize is set to zero, via either its setter or the object constructor.

Noncompliant Code Example

fun do() {

    val stpe1 = ScheduledThreadPoolExecutor(0) // Noncompliant

    val stpe2 = ScheduledThreadPoolExecutor(POOL_SIZE)
    stpe2.corePoolSize = 0 // Noncompliant

    ...
