      public static TypeBinding substitute(Substitution substitution, TypeBinding originalType)
      Returns a type, where original type was substituted using the receiver parameterized type. In raw mode (see Substitution.isRawSubstitution()), all parameterized types are converted to raw types. Cf. 4.8: "The type of a constructor (8.8), instance method (8.4, 9.4), or non-static field (8.3) M of a raw type C that is not inherited from its superclasses or superinterfaces is the raw type that corresponds to the erasure of its type in the generic declaration corresponding to C."
