Bug 32557

I (and Gump ;-) can confirm that.

JDK 1.5 is much smarter when it comes to handling the code in one of the test
files. 
public class E {
    E() {
        System.out.println(A.class);
    }
}

In JDK 1.5, thie uses a class reference in the produced class file to A, rather
than a string reference as used in previous versions. The code for the above has
gone from:

{
static java.lang.Class class$A;
  Synthetic: true

E();
  Code:
   Stack=3, Locals=1, Args_size=1
   0:   aload_0
   1:   invokespecial   #6; //Method java/lang/Object."<init>":()V
   4:   getstatic       #7; //Field java/lang/System.out:Ljava/io/PrintStream;
   7:   getstatic       #8; //Field class$A:Ljava/lang/Class;
   10:  ifnonnull       25
   13:  ldc     #9; //String A
   15:  invokestatic    #10; //Method class$:(Ljava/lang/String;)Ljava/lang/Class;
   18:  dup
   19:  putstatic       #8; //Field class$A:Ljava/lang/Class;
   22:  goto    28
   25:  getstatic       #8; //Field class$A:Ljava/lang/Class;
   28:  invokevirtual   #11; //Method
java/io/PrintStream.println:(Ljava/lang/Object;)V
   31:  return

static java.lang.Class class$(java.lang.String);
  Code:
   Stack=3, Locals=2, Args_size=1
   0:   aload_0
   1:   invokestatic    #1; //Method
java/lang/Class.forName:(Ljava/lang/String;)Ljava/lang/Class;
   4:   areturn
   5:   astore_1
   6:   new     #3; //class java/lang/NoClassDefFoundError
   9:   dup
   10:  aload_1
   11:  invokevirtual   #4; //Method
java/lang/ClassNotFoundException.getMessage:()Ljava/lang/String;
   14:  invokespecial   #5; //Method
java/lang/NoClassDefFoundError."<init>":(Ljava/lang/String;)V
   17:  athrow
  Exception table:
   from   to  target type
     0     4     5   Class java/lang/ClassNotFoundException

  Synthetic: true

}


to


E();
  Code:
   Stack=2, Locals=1, Args_size=1
   0:   aload_0
   1:   invokespecial   #1; //Method java/lang/Object."<init>":()V
   4:   getstatic       #2; //Field java/lang/System.out:Ljava/io/PrintStream;
   7:   ldc_w   #3; //class A
   10:  invokevirtual   #4; //Method
java/io/PrintStream.println:(Ljava/lang/Object;)V
   13:  return

}

Quite an improvment.

Is it just the test that is fixed, or the task? If the latter, might be a good
1.6.3 candidate.

Only the test code has changed. 

The only implication of this bug is that under JDK 1.5+, the <depend> code, as
it currently stands, will perform a little bit better than under previous JDKs.
 A source file which contains a reference to a class of the form "A.class" will
generate a classfile with a class reference to A. Sice <depend> uses class
references to build its dependency model, under JDK 1.5, that model will be more
accurate.
