@sureshanaparti so without these changes ACS won’t work with mysql 8.4 and 8.0 is to be end of life in two months. Should we merge? cc @abh1sar @harikrishna-patnala @nvazquez ?

@sureshanaparti can clarify, but I think this PR is just for testing and verification. All the tests passed with mysql8.4 on kvm.

@DaanHoogland @abh1sar I think, mysql 8.4 should work with the earlier java connector as well, but it's better to keep at least the major version in sync for the connector to avoid any issues later (else we can update it when any issues are found). I've triggered smoke tests with mysql 8.4 with 4.20 health check PR to confirm if it works with earlier connector or not, let's wait for the results.
