Something weird in JLS (or in JBuilder)

Hi, everyone!

I was looking at the Java Language Specification and wanted to test some code in JBuilder. My surprise was that what the JLS said was ok, JBuilder pointed as compile-time error (the code in JLS was an example of what is right an wrong in use of fields during initialization).

Topic in JLS:
8.3.2.3 Restrictions on the use of Fields during Initialization

Here is the code:


Can anyone tell me why JBuilder has a different result compiling the code above?

Thanks for all,
Marcos.

On more thing:

I am using JBuilder8 with JDK 1.4.1-b21

Thanks,
Marcos.

Why not tell us what Builder said, and how that differed from what you expected?

Ok, let�s see...

At the point I found the code differed from what JBuilder says I�ll put //not ok for JBuilder, ok?



And what I was expecting is that JBuilder pointed ok and not ok in the same place the JLS did.

I hope this makes things clearer.

Thanks,
Marcos

And, above, ok is said by JLS.

Both javac from JDK 1.4.2 and Jikes both agree with the JLS. JBuilder's wrong.

Is JBuilder giving any more specific error message?

Illegal forward reference on int y = x + 1; which seems correct to me as x isn't declared until further down.
Same on the use of j before declaration in
j = j + 1;
int k = j = j + 1;
int h = j++;


This is exactly where javac also barfs, so JBuilder is correct.


P.S. I'm using JB2005 Developer and JDK 1.5.0
P.P.S. Even if it were allowed it'd be extremely dirty code and reason for a serious spanking of the person that produced it.
