How to fix this error?

What were the steps that caused the error? Did you run Fierix or this exception was thrown when you wanted to upload file and see flamegraph?

If the error appeared when you run Fierix, you can try to exclude all methods of all classloaders: open Tools | Fierix | Configuration and add following pattern to exclude methods class name: *ClassLoader* method name: *
