Found during triage here: https://github.com/adoptium/aqa-tests/issues/6555#issuecomment-3263915085

jdk/jfr/jvm/TestChunkIntegrity.java , jdk/jfr/jvm/TestJFRIntrinsic.java - jvm crashed - no test changes, compared with jdk24, @key jfr is removed (in January, https://github.com/openjdk/jdk25u/commit/99002e4f9d421d08d912187a1f01809d85820427), which shouldn't affect test itself. Also, @required vm.flagless added, then removed (in January, https://github.com/openjdk/jdk25u/commit/8f7e6e2dbc0a3ccf56242bf071e57bfd671de951).
