Hello,

I am using the Yourkit Java Profiler 2024.9-b165 (license) , the profiled application is getting crashed with the below error while doing remote profiling. The profiled application is running on a Linux x64 on Zulu openJDK 11 Wildfly 26.1.3.

java.lang.NoClassDefFoundError: com/yourkit/runtime/Callback
at org.hibernate@5.3.28.Final//org.hibernate.internal.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:494)
at

Thanks

Version 2024.9 is end-of-life. Please use the latest version, 2025.3. If the problem is reproducible with version 2025.3, please send the log file from the YourKit profiler agent to support@yourkit.com. The log file is located in the ~/.yjp/log directory.
