I want to do distributed tracking using Java APM. Initially, we use Java agent as manual setup with -javaagent flag and we get tracing data using this. Then we deploy this on our test server and its working fine. Now, to take this on production server, i try to add Java APM as dependency but its throwing error as follows: [INFO] --- spring-boot-maven-plugin:2.1.6.RELEASE:run (default-cli) @ demo --- [INFO] Attaching agents: 2019-07-29 10:41:47.841 [Attach Listener] INFO co.elastic.apm.agent.configuration.StartupInfo - Starting Elastic APM 1.7.0 as first on Java 1.8.0\_212 (Oracle Corporation) Linux 4.18.0-25-generic 2019-07-29 10:41:47.841 [Attach Listener] WARN co.elastic.apm.agent.configuration.StartupInfo - To enable all features and to increase startup times, please configure application\_packages 2019-07-29 10:41:47.925 [apm-server-healthcheck] INFO co.elastic.apm.agent.report.ApmServerHealthChecker - Elastic APM server is available: { "build\_date": "2019-06-20T14:39:23Z", "build\_sha": "9a099b63c53eac8c55707df96193143ec66337e9", "version": "7.2.0"} Exception in thread "restartedMain" java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.springframework.boot.devtools.restart.RestartLauncher.run(RestartLauncher.java:49) Caused by: java.lang.IllegalStateException: Error during attachment using: co.elastic.apm.attach.bytebuddy.agent.ByteBuddyAgent$AttachmentProvider$Compound@867f9f9 at co.elastic.apm.attach.bytebuddy.agent.ByteBuddyAgent.install(ByteBuddyAgent.java:427) at co.elastic.apm.attach.bytebuddy.agent.ByteBuddyAgent.attach(ByteBuddyAgent.java:298) at co.elastic.apm.attach.bytebuddy.agent.ByteBuddyAgent.attach(ByteBuddyAgent.java:273) at co.elastic.apm.attach.ElasticApmAttacher.attach(ElasticApmAttacher.java:84) at co.elastic.apm.attach.ElasticApmAttacher.attach(ElasticApmAttacher.java:55) at com.example.demo.DemoApplication.main(DemoApplication.java:11) ... 5 more Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at co.elastic.apm.attach.bytebuddy.agent.Attacher.install(Attacher.java:99) at co.elastic.apm.attach.bytebuddy.agent.ByteBuddyAgent.install(ByteBuddyAgent.java:422) ... 10 more Caused by: java.lang.UnsatisfiedLinkError: Native Library /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/libattach.so already loaded in another classloader at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1907) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1845) at java.lang.Runtime.loadLibrary0(Runtime.java:870) at java.lang.System.loadLibrary(System.java:1122) at sun.tools.attach.LinuxVirtualMachine.(LinuxVirtualMachine.java:342) at sun.tools.attach.LinuxAttachProvider.attachVirtualMachine(LinuxAttachProvider.java:63) at com.sun.tools.attach.VirtualMachine.attach(VirtualMachine.java:208) ... 16 more We are using Java APM version :1.7.0 Code in pom.xml: co.elastic.apm apm-agent-attach 1.7.0 ---

Sorry for not responding here - this was an oversight. Generally it's better to not re-create the issue ([Not able to add JAVA APM agent as dependency in spring boot project](https://discuss.elastic.co/t/not-able-to-add-java-apm-agent-as-dependency-in-spring-boot-project/193224)) but to ping on the same thread. ---
