The reason for my confusion:

 From the JLS, ??17.5.3:
"If a final field is initialized to a compile-time constant ... uses of that
final field are replaced at compile time with the compile-time constant."

Details in ??15.28:
"A compile-time constant expression is an expression denoting a value of
primitive type or a String that does not complete abruptly and is composed
using only the following:
  . . .

  o Simple names that refer to constant variables (??4.12.4).

??4.12.4:
"We call a variable, of primitive type or type String, that is final and
initialized with a compile-time constant expression (??15.28) a /constant
variable/."
