I try to update the apm agent from 1.17.0 to 1.18.1.
But get the error below: (The same error occurs with 1.18.0 as well.)
Hi @suikast42,
It seems that bytecode modification applied by the agent may cause this error.
Is it reproducible systematically ?
Can you try to start the agent with log_level=debug and give us the name of the instrumentation classes that are applied to this method ? using cat agent.log | grep 'StcRepository' | grep 'Method match'
Also, can you provide the exact JVM version and vendor that you are using ? (output of java -version would provide this).
Also, what could help here would be to get the modified bytecode for this class, you can instruct the agent to dump that to filesystem by:
- creating a temporary folder
/tmp/bytebuddy-dump - add
-Dco.elastic.apm.agent.shaded.bytebuddy.dump=/tmp/bytebuddy-dumpto your JVM options
Then, if that particular class is modified by our agent, there should be multiple versions of that class suffixed with timestamp in the /tmp/bytebuddy-dump folder, you can attach those so we can analyze what could be wrong here.
Sorry for late response. I am at commissioning since few weeks.
But try this as soon as possible
