Make sure that your jforum-custom.conf file has the following option set:

database.support.autokeys=true

MySQL uses autoincrement fields to create record id's. The section of code that your StackTrace points to is for DB's that don't have support autoincrement fields.

You should probably also verify that all the settings in the config/database/mysql/mysql.properties are correctly defined in your config file as well.
