I am trying to migrate my application from Java 8 to OpenJDK 11. I used MySql connector version 5 and its working fine. Is it required to upgrade MySql connector JAR to version 8.0? I read about it from below link but they don't mention about Java 11.
https://dev.mysql.com/doc/connector-j/5.1/en/connector-j-versions-java.html
According to your reference, and this, we clearly can see that, MySQL connector version 5 uses JDBC version 3.0, 4.0, 4.1, 4.2.
MySQL connector version 8 uses JDB version 4.2.
Although JDBC version 4.2 supports JDK version 1.8.x, the new (for today) JDBC version 4.3 supports JDK version 9.
So, we wait new version of the JDBC, which supports JDK 11, then wait until MySQL supports new version of JDBC driver.
