> public Map<String, String> getMisc()
> results in this create table statement:
> create table User_misc (User_id bigint not null, element varchar(255), key varchar(255), primary key (User_id, key)) type=InnoDB
> But "KEY" is a reserved word, so MySQL won't create that table. The default column name should either change or be enclosed by backticks.
