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

public void do(){

  ScheduledThreadPoolExecutor stpe1 = new ScheduledThreadPoolExecutor(0); // Noncompliant

  ScheduledThreadPoolExecutor stpe2 = new ScheduledThreadPoolExecutor(POOL_SIZE);
  stpe2.setCorePoolSize(0);  // Noncompliant
