"If a type name is of the form Q.Id, then Q must be either a type name
or a package name. If Id names exactly one type that is a member of the
type or package denoted by Q, then the qualified type name denotes that
type.

If Id does not name a member type within Q (8.5,9.5), or the member type
named Id within Q is not accessible (6.6), or Id names more than one
member type within Q, ***or Id names a static member type (8.5.2) within
Q and Q is parameterized***, then a compile-time error occurs."
