Yes, but in those cases the user should be informed .  The user can then look at the libs on the runtime system and see if there are any candidates causing the issue (like in our RHEL aarch64 example).
There is already the option to trigger an assert  (but few users will run (fast)debug binaries)  and the option to get information from UL (but who will have UL  enabled - for sure not all users).  But quite a few people use JFR so it is a nice way to get the info 'recorded' .
