A DESCRIPTION OF THE PROBLEM :
TypeMirror's documentation says that a the result of a toString() should try to be valid to use in source code.



    /**
     * Returns an informative string representation of this type. If
     * possible, the string should be of a form suitable for
     * representing this type in source code. Any names embedded in
     * the result are qualified if possible.
     *
     * @return a string representation of this type
     */




STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Make an annotation whose target is TYPE_USE

@Target({ElementType.TYPE_USE})
@interface ExampleAnn {}

2. Write some code which uses that annotation on a field type

class Example {
    @ExampleAnn String abc;
}

3. Obtain a TypeMirror of the VariableElement via an annotation processor.

4. Using .toString() on that TypeMirror


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
java.lang.@ExampleAnn String
ACTUAL -
@ExampleAnn java.lang.String
