When trying to stop server in jmx integration tests I get error that is in error.txt.

Repo: https://github.com/lgrossma/jbosstools-server/tree/jmx-smoke
open jbosstools-server/as/itests/org.jboss.tools.as.jmx.ui.bot.itests in terminal -> mvn clean install -PITests -Pdownload-jbt -> wait for one of the tests to "finish" and after method which should stop server
Currently using workaround to terminate server via console
