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.
