Description:
I'm using springboot3.2,HikariCP or Druid connection pool initialization in jdk21 and mysql-connector-j 8.4.0 will encounter that the arm64 m1pro soc macbook connection duration is exactly 30 seconds, using linux intel server initialization speed also takes more than 2 seconds, Neither mysql-Connector-J 8.3.0 nor mysql-Connector-J 8.2.0 will experience this situation and the macbook 30 seconds is a fixed time, presumably some sort of mysql server connection and jdbc compatibility issue will hopefully be resolved,my mysql server version is MySQL (ver. 8.0.26-16

How to repeat:
springboot3.2+jdk21+mysql-connector-j 8.4.0 + mybatis plus + druid or HikariCP
First connection MySQL (ver. 8.0.26-16

Suggested fix:
init connection bug
