During compile the following simple code

class test {
    public static void main (String [] args) {
        int i = (i = 10) + i++;
        int n = (n = 0);
    }
}

I've got the error message:

<cos@ultrasparrow: ~/temp(318)> /usr/java1.3/bin/javac -server test.java
test.java:3: illegal forward reference
        int i = (i = 10) + i++;
                           ^
1 error

With Java1.2 it has been compiled pretty fine.
