Description:
https://github.com/mysql/mysql-connector-j/blob/release/5.1/src/com/mysql/jdbc/TimeUtil.ja...

com.mysql.jdbc.TimeUtil#getDefaultTimeZone(boolean) 

   public static final TimeZone getDefaultTimeZone(boolean useCache) {
        return (TimeZone) (useCache ? DEFAULT_TIMEZONE.clone() : TimeZone.getDefault().clone());
    }

How to repeat:
   public static final TimeZone getDefaultTimeZone(boolean useCache) {
        return useCache ? DEFAULT_TIMEZONE.clone() : TimeZone.getDefault();
    }

This bug does not exist in the latest Connector/J 8.0.

Connector/J 5.1 series came to EOL on Feb 9th, 2021, see https://www.mysql.com/support/eol-notice.html, so this bug will not be fixed there.
