Java Flight Recorder — missing File Write/Read events
Question
I am analyzing java8 JVM-process with Java Mission Control + Flight Recorder.
When checking the recording under I/O tab, it says:
"Event types 'File Write' 'File Read' are not enabled in this recording"
When creating the recording, in the recording wizard, last dialog Event Details... , as far as I can see, everything already has Enabled=True , but I cannot find any setting for File Write/Read ...
How do I enable them?
