I backport this for parity with 17.0.18-oracle.
First, there was the attempt to delete these events, see backport of https://bugs.openjdk.org/browse/JDK-8291733: Remove JFR events that expose hashtable
@eghalin pointed out to me that Oracle reverts this (See JDK-8369975 [BACKOUT BACKPORT] Remove JFR events that expose hashtable) and instead disables the events,
see also comment in #4047
This now implements the backport according to that comment.
Thanks again, Eric, for informing about this.
