I'm using Tomcat 9.x and it works fine with the latest IDEA (2023.1). It could be a problem with Tomcat 8.5.x, will check it.

Yes, it worked when i use Tomcat 8.5.87 or Tomcat 9.x. It's possible that there could be a bug with Tomcat 8.5.35 . Thanks.

@mumaxiaozi You could check the conf/server.xml of the Tomcat 8.5.35, to see if the following element existing.

<Server>
   <Service name='Catalina'>
     <Connector protocol='HTTP/1.1'>

Oh my god , the server.xml existing this configuration. 

    <Connector port="8080" protocol="org.apache.coyote.http11.Http11AprProtocol"
               connectionTimeout="20000"
               redirectPort="8443"
           acceptCount="2000" />

It worked when I modify this config like this.

     <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
           acceptCount="2000" />

Thanks a million.
