Calm down, it is a harmless folksy anecdotal comment on two technologies (ironically trademarked by the same company).
Java is a technology (including web plugins) that has received a lot of criticism from the community. Just recently the Department of Homeland Security had to chime in and recommend that users disable Java due to security concerns. MySQL has always received criticism due to various issues.
That makes absolutely no sense what so ever. Java is the dominate enterprise development platform.
MySQL is most popular in non-enteprise environments.
