Hi, You can switch output mode from file to tcpserver or tcpclient to obtain dump prior to killing of JVM. Or set jmx option to true to activate mbean and using it request dump into file prior to killing of JVM. Description of those options can be found at http://www.eclemma.org/jacoco/trunk/doc/agent.html
