How to resolve 'This stream is not writable' Tomcat error?

If you are seeing this stack trace in your PDE Log and have HTTP 2.0 configured on your Tomcat 9 server, you may be encountered an issue where the HTTP 2.0 connection closed due too much overhead. 

org.apache.catalina.authenticator.FormAuthenticator.forwardToErrorPage Unexpected error forwarding to error page org.apache.catalina.connector.ClientAbortException: org.apache.coyote.CloseNowException: Connection [1031], Stream [11], This stream is not writable

To resolve the issue, you will need to set the overhead threshold to 0. 

• First Stop Tomcat 
• Edit the server.xml file to set the overhead threshold. Similar to this example. 

 <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol"         overheadDataThreshold=0  />

•  Start Tomcat 

This should resolve the error message.
