I'm trying to modify the value of MaxConcurrentStream for the tomcat server in order to check that it returns a STREAM_REFUSED when the client uses more streams, but I don't manage to change the default unlimited value.
I've been inspecting the tomcat server code with a debugger and I saw it enters the method protected synchronized void set(Setting setting, Long value) from the org.apache.coyote.http2.ConnectionSettingsLocal.java class to change the value for maxConcurrentStream. Yet, if I'm not wrong, it only modifies the pending hashSet not the current one, which is the one that is checked later on to determine if it is lower than the clients' active streams and therefore send the STREAM_REFUSED code. I'm not sure if I'm not modifying the value correctly. I use the Http2Protocol's method setMaxConcurrentStreams to set the value and then add the Http2Protocol to the connector(addUpgradeProtocol). I'd be grateful if someone could give me a hint of what is going on or what I'm doing wrong. Thank you!
