Secondary tables and associations (join tables) are really two different things. A secondary table allows you to map your entity properties to
multiple tables. @JoinTable on the other hand are used to map associations and configure certain properties of the join table.
One does not require the other. I am not sure what makes you believe that using @JoinTable requires the use of @SecondaryTable.
If you after some examples have a look at the JPA spec as well. It is a good starting point.
Regarding the metamodel branch, I am not sure about the binders and so on, but afaicr the sources does not imply the link
between join table and secondary table.
