@jerboaa Thanks - I did run the tier1 suite locally before creating the PR. I also enabled GHA for the for the fork, but did that after creating the PR so I don't think that it automatically triggered - I now triggered a run which seems to have passed: https://github.com/antonha/jdk21u-dev/actions/runs/7646727789

I'm not that familiar with the test suite so I don't quite know which JFR tests there are, but I did now try running the `jdk/jfr` tests using `make run-test TEST=jdk/jfr` for `linux-x86_64-server-release` and `linux-x86_64-server-fastdebug` locally, both pass with the same message:


==============================
Test summary
==============================
   TEST                                              TOTAL  PASS  FAIL ERROR   
   jtreg:test/jdk/jdk/jfr                              584   584     0     0   
==============================
TEST SUCCESS


Should I re-apply for approval now?
