A DESCRIPTION OF THE PROBLEM :
This section:

http://java.sun.com/docs/books/jls/second_edition/html/classes.doc.html#229267

Contains this example:

class Top {
int x;
class Dummy {
Dummy(Object o) {}
}
class Inside extends Dummy {
Inside() {
super(new Object() { int r = x; }); // error
}
Inside(final int y) {
super(new Object() { int r = y; }); // correct
}
}
}

Notice the "//error" comment. But javac *does* compile this without any error.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Try to compile the above program.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The compiler should emit an error, as hinted in JLS
ACTUAL -
No error - it compiles successfully.

REPRODUCIBILITY :
This bug can be reproduced always.
