下面是这种情况：
- WebSocket的服务器正在运行
- 泰鲁斯客户端共享容器被启用
- 泰鲁斯 - 客户端连接到服务器（一切都很好）
- WebSocket伺服器重新启动
- 泰鲁斯 - 客户端无法连接到服务器，并抛出即使在服务器启动以下异常：
javax.websocket.DeploymentException: Connection failed
- 如果客户端应用程序重新启动它可以重新连接到服务器
注意：如果不会发生此问题泰鲁斯客户共享容器被禁用。
堆栈跟踪：
javax.websocket.DeploymentException: Connection failed.

该NPE从行来if (runners.length == 1) {在灰熊的项目文件RoundRobinConnectionDistributor.java:146
private final class SharedIterator implements Iterator {
private final AtomicInteger counter = new AtomicInteger();
@Override
public SelectorRunner next() {
final SelectorRunner[] runners = getTransportSelectorRunners();
if (runners.length == 1) {
return runners[0];
}
return runners[(counter.getAndIncrement() & 0x7fffffff) % runners.length];
}
@Override
public SelectorRunner nextService() {
return next();
}
}
看起来像runners是null 。
