'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
}
