描述你遇到了什么问题

用户点播视频，PC端使用WebRtc播放，当用户关闭视频后，云服务器利用回调函数，主动踢掉用户播放的视频流，该过程进行十几次后，云服务器的CPU一直处于98%的状态，即使没有任何推流操作，cpu也无法得到释放。

Describe the Bug

The JSON response sent back over HTTP doesn't encode certain characters correctly.

For example, if a value in a string column contains the char \1 the byte value is copied verbatim in the response, breaking the client:

>>> json.loads('"\1"')

Instead, we shou

Otherwise we got WARNING: package com.ibm.lang.management.internal not in jdk.management in logs

 .writeTo(Sinks.logger());

I'd like aggregator to be something requiring a non-serialisable dependency to do its work.

I know I can do this:

Pipeline p = Pipeline.create();
p.readFrom(TestSource
