In a different discussion, I have been told previously that the title of the CSR and the JBS issue for which the CSR is created, should match. I think we should change the title of https://bugs.openjdk.org/browse/JDK-8341566 to match what you have for the CSR, since that one is more clear. ------------- PR Comment: https://git.openjdk.org/jdk/pull/21371#issuecomment-2401594697
