YourKit Profiler 2015.15074 + Mule ESB = False

Hi!
Trying to profile an instance of the Mule ESB with YJP but get this log when Mule is starting up:

Mule ESB is running on Java 7 under Ubuntu. Nothing particular in the YJP logs.
I will probably be able to work around this in some way, just thought you wanted to know.
Best regards,
Ivan

Hi,

[YourKit Java Profiler 9.0.8] Loaded. Log file: /home/xxxx/.yjp/log/22339.log

It seems you're using extremely old version 9 which is unsupported for years.

Please ensure you use the latest version 2015.

Best regards,
Anton

Thanks!
I was using the YourKit Profiler libraries bundled with Mule ESB.
For others in the same situation:
- Remove the old library files in the Mule instance's directory $MULE_HOME/lib/native/profiler.
- Copy the files from the appropriate library folder in the YourKit Linux download (libyjpagent.so and yjp_dc in my case) to the $MULE_HOME/lib/native/profiler directory.
- Rename the libyjpagent.so file to match the name of the old library file. If you start Mule with the -profile option and the name of the library is not correct, it will log a message with the correct name of the library to use.

You are now ready to start Mule with the -profile option.

Hello Ivan

Thank you for the feedback and for providing such detailed workaround.

Are you using the latest version of Mule ESB? Perhaps we should contact its vendor and ask to update the bundled agent library.

Best regards,
Anton
