I see this behavior with Wildfly 16 and wildfly 22: When i enter the jboss-cli console and shutdown the wildfly server, I can't quit the session because it will result in a fully hanging SSh session.
The error message is quite odd:
CLI Terminal Connection (uninterruptable)" java.io.IOError: java.io.IOException: Error executing 'stty icrnl ixon echo echoctl icanon iexten eof ^D intr ^C min 11111111111111111111111111111111 time 11111111111111111111111111111111': stty: invalid integer argument: '11111111111111111111111111111111': Value too large for defined data type
