BETA_JAVA8:

Given the following program:

// ---
import java.lang.annotation.*;
import static java.lang.annotation.ElementType.*; 
@Target(TYPE_USE)
@interface Immutable {}
class Document {}
class X {
	@Immutable X() {
	}
}
// ---

The annotation @Immutable does not make it to the class file.

  X();
    descriptor: ()V
    flags: 
    Code:
      stack=1, locals=1, args_size=1
         0: aload_0       
         1: invokespecial #1                  // Method java/lang/Object."<init>":()V
         4: return        
      LineNumberTable:
        line 7: 0
        line 8: 4
    RuntimeInvisibleTypeAnnotations:

Ensure the annotations on the constructor make it to the class file.
