'ScheduledThreadPoolExecutor' with zero core threads

Reports any java.util.concurrent.ScheduledThreadPoolExecutor instances in which corePoolSize is set to zero via the setCorePoolSize method or the object constructor.

A ScheduledThreadPoolExecutor with zero core threads will run nothing.

Example:

  void foo(int corePoolSize) {
      if (corePoolSize != 0) return;
      ThreadPoolExecutor executor = new ScheduledThreadPoolExecutor(corePoolSize); // warning
      executor.setCorePoolSize(corePoolSize); // warning
  }
