Frequent warn message: Could not find Java_java_lang_ClassLoader_00024NativeLibrary_load

See original GitHub issue

Agent version: 1.33.0 Java version: SapMachine (build 11.0.16+8-LTS-sapmachine) (OpenJDK fork)

Hey there,

recently we updated our Java version from 11.0.14.1 to the aforementioned version and switched from agent version 1.30.1 to 1.33.0. We’re use the matching debug symbols for the agent’s profiling feature.

Since updating the version the apm agent frequently logs the following warning: WARNING: Could not find Java_java_lang_ClassLoader_00024NativeLibrary_load

I raised an issue at the SapMachine project. The engineers investigated the issue and came to the conclusion that the latest apm agent uses an older version of the async-profiler where the problematic code is still present.

See this comment for reference.

Would you please comment on this issue? Will you fix it by upgrading the async-profiler version?

Thanks in advance.

Kind regards.
