I don't at first glance see a mapping of the regular expression "+" (one or 
more) to something in the JLS grammar. There are

        ?       =>      [x]             zero or one x
        *       =>      {x}             zero or more x

but nothing (succinct at least) apparent for the plus sign.

Thanks,

Brian
