@tajila pls take a look. We are looking to enable jdk_jmx tests and this will be the remaining failure. We can exclude the test until it's fixed.

Thanks, we will need to exculde this for some time. Currently, we only have internal JFR support.

Could you fix the FlightRecorderMXBean and Impl to remove the methods that don't work? Presumably some of it works since it's been added, or the whole thing could be removed..
