Description Reid Jones CLA 2002-11-18 14:04:34 EST 
Through some recent fixes in sun's j2sdk1.4.1, certain forward references of 
static variables are allowed. The following code compiles and runs using 
1.4.1's javac, but not in Eclipse 2.0:

public class Test {
  public Test(){
    super();
    System.out.println(error);
  }

  public static void main (String args[]) {
    Test test = new Test();
  }

  static {
     error = "Hello World";
  }
  private static String error;
}

I looked for this in other bug reports but could not find it.

No, this is definitely new. Need to check the spec.
Comment 2 Olivier Thomann CLA 2002-11-18 17:35:02 EST 
Jikes 1.15 rejects it, but Jikes 1.17 accepts it.

Olivier - can you please look for a URL to this bug in javac database ?

This is a link pointing to this problem.

If the reference is an assignement, then it should not complain about an invalid
forward reference. See latest specs:
http://java.sun.com/docs/books/jls/second_edition/html/classes.doc.html#287406

Jacks test suite has some related tests.

Indeed the spec is pretty clear, assignments should be allowed to perform on 
forward references.
Comment 7 Philipe Mulet CLA 2002-12-04 06:15:21 EST 
Assignments will no longer complain about forward references.
Fixed.

Verified.
