 We can see the problem on 8.5.84, the problem is when we configure server.xml
connector of the protocol is org. Apache. Coyote. Http11. Http11Nio2Protocol.
This is not an issue when changing to the default configuration (Nio).
  In tests, when Nio mode was set, the problem was fixed after 8.5.60, but when
Nio2 mode was set, the problem existed on versions 8.5.60, 8.5.75, 8.5.84, etc.
