Java Agent and Tomcat shutdown
Hello, we are using a java agent to start a listening process (JMX proxy). The systemd file for tomcat looks like (snippet): JAVA_OPTS=... -javaagent:/opt/runtime/jmxagent/jmxagent.jar -Dorg.goktay.rmiregistry.port=15000 -Dorg.goktay.rmiserver.port=15001 ExecStart=/opt/apache-tomcat/bin/catalina.sh run ExecStop=/opt/apache-tomcat/bin/catalina.sh stop 60 When starting the service, everything works fine and the java agent is accessible via the opened port 15000. However, when stopping tomcat, it seems that a java process is started and tries to open the same port again: 2670]: Exception in thread "main" java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:568) at java.instrument/sun.instrument.InstrumentationImpl.loadClassAndStartAgent(InstrumentationImpl.java:493) at java.instrument/sun.instrument.InstrumentationImpl.loadClassAndCallPremain(InstrumentationImpl.java:503) Caused by: java.rmi.server.ExportException: Port already in use: 15000; nested exception is: java.net.BindException: Address already in use at java.rmi/sun.rmi.transport.tcp.TCPTransport.listen(TCPTransport.java:346) at java.rmi/sun.rmi.transport.tcp.TCPTransport.exportObject(TCPTransport.java:243) at java.rmi/sun.rmi.transport.tcp.TCPEndpoint.exportObject(TCPEndpoint.java:415) at java.rmi/sun.rmi.transport.LiveRef.exportObject(LiveRef.java:147) at java.rmi/sun.rmi.server.UnicastServerRef.exportObject(UnicastServerRef.java:235) at java.rmi/sun.rmi.registry.RegistryImpl.setup(RegistryImpl.java:223) at java.rmi/sun.rmi.registry.RegistryImpl.(RegistryImpl.java:208) at java.rmi/java.rmi.registry.LocateRegistry.createRegistry(LocateRegistry.java:203) at org.goktay.jmx.JMXAgent.premain(JMXAgent.java:33) ... 6 more Caused by: java.net.BindException: Address already in use at java.base/sun.nio.ch.Net.bind0(Native Method) at java.base/sun.nio.ch.Net.bind(Net.java:555) at java.base/sun.nio.ch.Net.bind(Net.java:544) at java.base/sun.nio.ch.NioSocketImpl.bind(NioSocketImpl.java:643) at java.base/java.net.ServerSocket.bind(ServerSocket.java:388) at java.base/java.net.ServerSocket.(ServerSocket.java:274) at java.base/java.net.ServerSocket.(ServerSocket.java:167) at java.rmi/sun.rmi.transport.tcp.TCPDirectSocketFactory.createServerSocket(TCPDirectSocketFactory.java:45) at java.rmi/sun.rmi.transport.tcp.TCPEndpoint.newServerSocket(TCPEndpoint.java:673) at java.rmi/sun.rmi.transport.tcp.TCPTransport.listen(TCPTransport.java:335) ... 14 more *** java.lang.instrument ASSERTION FAILED ***: "result" with message agent load/premain call failed at src/java.instrument/share/native/libinstrument/JPLISAgent.c line: 422 The premain method is entered again and of course the port is already used. Is there a way to stop tomcat without re-entering the java agent? Using shutdown.sh shows the same problem. Thanks in advance!
