It's a new issue.

Could you please provide the problematic snapshot file. We would appreciate if you could compress it (e.g. zip) and share with us by using a service like Google Drive or DropBox. Please send the download link to [email protected]

Best regards,

Meanwhile, could you please check if the following proposed fix solves the problem:
- download this yourkit.jar https://www.yourkit.com/download/tmp/20 ... ourkit.jar
- write it over <profiler installation directory>/lib/yourkit.jar
- restart the profiler and open the same HPROF snapshot.

If it still fails, please let us know the new error.
