I haven't been able to verify RHBQ MySQL extensions in FIPS-enabled environment as current test QE test coverage is failing due to MySQL container setup. I am positive this only requires a time investment and we will be able to verify it with next release, but support cannot be declared until we have proper test coverage run with OpenJDK 17 / 21 and we test JVM and native mode.
This is next step after the FIPS support documented in QUARKUS-3225.
