跟踪下来原因是因为dubbo3的异步模式，如果某个Filter抛异常导致org.apache.dubbo.rpc.cluster.filter.FilterChainBuilder.CallbackRegistrationInvoker#invoke不会正常结束，asyncResult.whenCompleteWithContext对应的回调不会执行。
public Result invoke(Invocation invocation) throws RpcException {
Result asyncResult = filterInvoker.invoke(invocation);
asyncResult.whenCompleteWithContext((r, t) -> {
for (int i = filters.size() - 1; i >= 0; i--) {
//如果某个filter抛异常，这里代码不会执行
}
});
return asyncResult;
}
