这里应该是Runnable failRunnable = (Runnable) fail;

1.从代码上看只是开放了setCapacity的入口，且capacity是通过volatile修饰的，所以capacity的变化会及时通知到各个线程，
关键问题是，当我往队列里插入或者取对象的时候，会有个判断
public void put(E e) throws InterruptedException {
if (e == null) throw new NullPointerException();
// Note: convention in all put/take/etc is to preset local var
// holding count negative to indicate failure unless set.
int c = -1;
ResizableCapacityLinkedBlockIngQueue.Node node = new ResizableCapacityLinkedBlockIngQueue.Node(e);
final ReentrantLock putLock = this.putLock;
final AtomicInteger count = this.count;
putLock.lockInterruptibly();
try {
/*
* Note that count is used in wait guard even though it is
* not protected by lock. This works because count can
* only decrease at this point (all other puts are shut
* out by lock), and we (or some other waiting put) are
* signalled if it ever changes from capacity. Similarly
* for all other uses of count in other wait guards.
*/
while (count.get() == capacity) {
notFull.await();
}
enqueue(node);
c = count.getAndIncrement();
if (c + 1 < capacity)
notFull.signal();
} finally {
putLock.unlock();
}
if (c == 0)
signalNotEmpty();
}

如果这个时候我调整了假设当前的任务数量是100，capacity是200，现在我调整capacity的大小为50，这个时候根据这个判断count.get() == capacity，任务队列是没有满的，这样还会往队列里塞数据，不知道我理解的对不对，是不是调整为count.get()>=capacity

你好，我尝试下了在项目中设置 cat.servers 服务器,好像不起作用呀，
还得通过CAT_HOME/client.xml 来设置servers 才行呀，
debug 跟了下 代码发现 DefaultClientConfigManager 类默认就是加载 cat_HOME 下的client.xml 文件中的 Server

如果动态修改线程池参数的话，服务重启后，之前修改的线程池参数还有效嘛

能否增加日记组件，增加traceId标识
