Alex Rudyy commented on QPID-8376:
----------------------------------
[~rgodfrey], as part of implemented changes the calls to
{{Method#setAccessible(true)}} are added to make methods {{getProcessCpuTime}}
and {{getProcessCpuLoad}} publicly accessible. Those method accessibility
change calls fail on JDK 11 and above with exception
{{java.lang.reflect.InaccessibleObjectException}} being thrown. Taking that
modified methods are already public, the calls to change accessibility seem
redundant. I looked through Oracle JDK 8, Open JDK 11-12 and IBM JDK 8 to
verify the visibility of methods {{getProcessCpuTime}} and
{{getProcessCpuLoad}}. The methods are public on the JDKs I looked through. I
would suggest to remove the calls to {{Method#setAccessible(true)}} or add an
exception handling logic for the calls (if there are JDKs with non-public
methods {{getProcessCpuTime}} and {{getProcessCpuLoad}})
