Java version openjdk 21-ea 2023-09-19 OpenJDK Runtime Environment (build 21-ea+23-1988) OpenJDK 64-Bit Server VM (build 21-ea+23-1988, mixed mode, sharing) Startup flags java -Dappdynamics.jvm.shutdown.mark.node.as.historical=true -Dappdynamics.agent.log4j2.disabled=true -javaagent:/appdynamics/javaagent.jar From what I understand this version of the agent should work with openjdk21 but please correct me if i'm wrong.. any suggestions on what I can do to get this to startup? At startup I see below log. Which to me means the agent can't startup because of an incompatible java version Class with name [com.ibm.lang.management.internal.ExtendedOperatingSystemMXBeanImpl] is not available in classpath, so will ignore export access. java.lang.ClassNotFoundException: Unable to load class io.opentelemetry.sdk.autoconfigure.spi.ResourceProvider at com.singularity.ee.agent.appagent.kernel.classloader.Post19AgentClassLoader.findClass(Post19AgentClassLoader.java:88) at com.singularity.ee.agent.appagent.kernel.classloader.AgentClassLoader.loadClassInternal(AgentClassLoader.java:456) at com.singularity.ee.agent.appagent.kernel.classloader.Post17AgentClassLoader.loadClassParentLast(Post17AgentClassLoader.java:81) at com.singularity.ee.agent.appagent.kernel.classloader.AgentClassLoader.loadClass(AgentClassLoader.java:354) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:526) at java.base/java.lang.Class.forName0(Native Method) at java.base/java.lang.Class.forName(Class.java:497) at java.base/java.lang.Class.forName(Class.java:476) at com.singularity.ee.agent.appagent.AgentEntryPoint.createJava9Module(AgentEntryPoint.java:800) at com.singularity.ee.agent.appagent.AgentEntryPoint.premain(AgentEntryPoint.java:639) at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:103) at java.base/java.lang.reflect.Method.invoke(Method.java:578) at java.instrument/sun.instrument.InstrumentationImpl.loadClassAndStartAgent(InstrumentationImpl.java:491) at java.instrument/sun.instrument.InstrumentationImpl.loadClassAndCallPremain(InstrumentationImpl.java:503) [AD Agent init] Fri Aug 30 20:35:48 UTC 2024[DEBUG]: JavaAgent - Setting AgentClassLoader as Context ClassLoader [AD Agent init] Fri Aug 30 20:35:48 UTC 2024[DEBUG]: JavaAgent - Setting AgentClassLoader as Context ClassLoader java.lang.IllegalArgumentException: Unsupported class file major version 65 at com.appdynamics.appagent/com.singularity.asm.org.objectweb.asm.ClassReader.<init>(ClassReader.java:199) at com.appdynamics.appagent/com.singularity.asm.org.objectweb.asm.ClassReader.<init>(ClassReader.java:180) at com.appdynamics.appagent/com.singularity.asm.org.objectweb.asm.ClassReader.<init>(ClassReader.java:166) at com.appdynamics.appagent/com.singularity.ee.agent.appagent.services.bciengine.asm.PreTransformer.preTransform(PreTransformer.java:49) at com.appdynamics.appagent/com.singularity.ee.agent.appagent.kernel.JavaAgent.preloadAgentClassesForDeadlockProneJVM(JavaAgent.java:656) at com.appdynamics.appagent/com.singularity.ee.agent.appagent.kernel.JavaAgent.initialize(JavaAgent.java:404) at com.appdynamics.appagent/com.singularity.ee.agent.appagent.kernel.JavaAgent.initialize(JavaAgent.java:347) at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:103) at java.base/java.lang.reflect.Method.invoke(Method.java:578) at com.singularity.ee.agent.appagent.AgentEntryPoint$1.run(AgentEntryPoint.java:656)
