* @summary Type annotations on anonymous and inner class.
* Six TYPE_USE annotations are repeated(or not); Four combinations create
* four test files, and each results in the test class and 2 anonymous classes.
* Each element of these three classes is checked for expected number of the
* four annotation Attributes. Expected annotation counts depend on type of
* annotation place on type of element (a FIELD&TYPE_USE element on a field
* results in 2). Elements with no annotations expect 0.
* Source template is read in from testanoninner.template
