a flag/query/option for such as well.)
I'm cross-posting into the serviceability alias
where the latter part of this discussion likely belongs
and where you'll get more concrete information than
my musings above.
You are right. In the MBeans tab you'll see
com.sun.management.HotSpotDiagnostic. It defines the getVMOption
operation. Type CMSClassUnloadingEnabled into the text field and press
the getVMOption button and it will popup a dialog window with its
current and default value.
