An important performance fix was added to 8u302. We should add a rule which checks if it the recording was made on < 8u302 and if the NativeSample event was enabled.

"The version of OpenJDK 8 you are running is lacking an important performance fix. Upgrading to version 8u302 or later can, in some cases, improve your performance quite radically. See JDK-8266723 for more information. An alternative can be to disable any periodic events not needed, such as the NativeExecutionSample event.”
