Overlapping table names in the database--where to report the issue?

class Course{
}

class Person{
     static hasMany = [courses: Course]
}

class PersonCourse{
}

In Grails 1.1 against an Oracle database, the above code will make a single table called PERSON_COURSE. If there are foreign key constraints, the table will have all of them (which led, in our case, to some mutually exclusive constraints and about half a day of head-scratching until we figured it out). Where should I report this?
