Exception when using Log4J and a SNAPSHOT version of the agent

See original GitHub issue

Describe the bug

I see the following exceptions when using the 1.26.1-SNAPSHOT (168b714) on a JBoss EAP:

I use the following Configuration:

2021-10-01 09:48:03,752 [main] INFO  co.elastic.apm.agent.configuration.StartupInfo - enable_public_api_annotation_inheritance: 'true' (source: Java System Properties)

2021-10-01 09:48:03,753 [main] INFO  co.elastic.apm.agent.configuration.StartupInfo - enable_log_correlation: 'true' (source: Java System Properties)

However, the actual log correlation is working.

Steps to reproduce

  • Start a JBoss EAP with a SNAPSHOT version of the agent
  • Deploy a war which uses Log4j2
  • Create a trace

Expected behavior

There are no exceptions in the log

I’m getting different exceptions in my test but I think the underlying issue is that the classes from logback-ecs-encoder aren’t added to the IndyPluginClassLoader. Instead, they’re loaded by the agent class loader which can’t resolve the logback classes.

java.lang.NoClassDefFoundError: ch/qos/logback/core/encoder/EncoderBase

I’ll add a mechanism that allows plugins to add more than just the classes within the plugin package to the IndyPluginClassLoader.
