ダボスレッドプール拒否の方針

ネイティブ拒否投げ戦略が付属して例外情報のJDKは、情報は、から学ぶ価値がより価値投げ、十分に詳細に説明されていませんが、ポリシーを拒否するダボが書き直されました。

ネイティブ投げゴミ情報戦略が付属していますJDK：

// ThreadPoolExecutor的toString方法
/**
* Returns a string identifying this pool, as well as its state,
* including indications of run state and estimated worker and
* task counts.
*
* @return a string identifying this pool, as well as its state
*/
public String toString() {
    long ncompleted;
    int nworkers, nactive;
    final ReentrantLock mainLock = this.mainLock;
    mainLock.lock();
    try {
        ncompleted = completedTaskCount;
        nactive = 0;
        nworkers = workers.size();
        for (Worker w : workers) {
            ncompleted += w.completedTasks;
            if (w.isLocked())
                ++nactive;
        }
    } finally {
        mainLock.unlock();
    }
    int c = ctl.get();
    String rs = (runStateLessThan(c, SHUTDOWN) ? "Running" :
                    (runStateAtLeast(c, TERMINATED) ? "Terminated" :
                    "Shutting down"));
    return super.toString() +
        "[" + rs +
        ", pool size = " + nworkers +
        ", active threads = " + nactive +
        ", queued tasks = " + workQueue.size() +
        ", completed tasks = " + ncompleted +
        "]";
}

スレッドプール情報ダボでスローポリシーを拒否：

// com.alibaba.dubbo.common.threadpool.support.AbortPolicyWithReport
@Override
public void rejectedExecution(Runnable r, ThreadPoolExecutor e) {
    String msg = String.format("Thread pool is EXHAUSTED!" +
            " Thread Name: %s, Pool Size: %d (active: %d, core: %d, max: %d, largest: %d), Task: %d (completed: %d)," +
