Hi Aleksey,

I am currently travelling and I have not been following this in detail.

As I understand it, JDK-8196341, extended the signatures for the commit() methods, but the associated !INCLUDE_JFR section was not updated, causing compilation errors.

I have not checked everything in detail, but it seems the fix does add those missing signature(s).

I am ok with this from a JFR perspective.

Thanks for addressing
Markus

I retract this RFR in favor of proper fix on JFR side:
