I am having problems with my Spring Boot application with embedded Tomcat 9.x. If left idle for some time it produces this error below and then wont accept any more requests until I press the ENTER button. I am running it as a standalone app. The error below:
java.lang.IllegalArgumentException: Invalid character found in method name. HTTP method names must be tokens

it produces this error below and then wont accept any more requests until I press the ENTER button.
There is no reference to the Spring Framework in this stack. Can you share what makes you think this is a problem with Spring Boot? We will need a small sample and instructions on how to reproduce (a zip or a link to a github repo).

Thanks Snicoll. I do not know that its Spring Boot or Tomcat but that's what I am running and I have no idea why it freezes and stops accepting requests when left idle for some time. If there are no requests coming to the server after a half hour or more , most of the time it spits out that error with no requests coming through. Then when new requests start coming through the server just freezes and does not service the requests until I press the ENTER key on the keyboard. Below is an example of when the server was idle for some time then new requests started coming in. The errors seen in the log only started showing up after I pressed ENTER key. Then new requests were processed as normal. So I do not know I am just looking for help. Below the logs.
