Incorrect type annotation path with multi-variable declaration and mixed-array notation

In the following example, the type path for the annotation on 'y' should be the same as 'x', but it is instead the same as 'z'. The type of 'y' is int[], so using an [array, array] type path is incorrect. (It is the correct type path for 'z', however.)

=== T.java
import java.lang.annotation.ElementType;
import java.lang.annotation.Target;

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

class T {
  int @A [] x = {};
  int @A [] y, z [][];
}
