Confusing error for constructor proxy shadowing

[odersky]

Compiler version

3.3.0

Minimized example

class Number(n: Int)
val x = Number(3)

Output

2 |val x = Number(3)
  |        ^^^^^^
  |        Reference to constructor proxy for class Number
  |        shadows outer reference to object Number in package java.lang

Expectation

1. java.lang.Number cannot possibly be applied, so one could avoid the error
2. The error message could be better and could contain some suggestions how to fix the problem.

I just wanted to point out that this code compiles and run with no error

'class Number(n: Int)
val x = new Number(3)'
