OK, I don't know whether this is really a bug or just an obsolete message being
printed on the console, but I've reopened the ticket and added a pointer to
this discussion, and a link to exactly which commit it was that caused this
change in behavior (just before Clojure 1.5.0-RC4).

There *is* mutual exclusion on all Java output streams (as well as input

Hey Sean,
Your attempt worked because in Netty 4.0.0.Alpha8

When you annotate, is it a runtime or a compile-time error? I would be very
surprised if it happened at runtime (when the function is actuall called).

It is almost certain that the method you want to call is inherited from a

You should first make a minimal example that reproduces this. I've just
failed to do so with the following:
abstract class AbstractParent {
public void x() { System.out.println(x); }
}
public class ConcreteChild extends AbstractParent {
}
user (set! *warn-on-reflection* true)
true
user (.x
I did it: the method must be final. Apparently without that the child is
compiled with an overriding method that I didn't even define!

Detailed finding: it *doesn't* fail at compile time; it always fails at
runtime.
Reason: at compile time there is a *reflection warning*, which means that
the method wasn't found and a reflective call was emited by the compiler.

You didn't recompile everything, that's the reason. I got the same error
the first time, that's how I realized that the child had overridden the
method. This is an interesting finding in itself: javac provides the
override precisely to avoid pitfalls such as this one. If the parent was

Hm. You shouldn't have made ConcreteChild a nested class, that is a

to have as many package-private classes as you wish; the constraint is only
on one *public* class. If you had ConcreteChild.java with this in it:

Yes, I'd say there is no low-level magic about those vars except that they
are well-supported in all the relevant contexts. However, the fact that

Still, it would be nice to understand whether it's possible to achieve the
same effect as Clojure core's settable vars.
It is, because clojure doesn't do anything magic here (apart from the
effects its set!-able vars have ;-).
The catch is:
The repl's thread binding for those vars is set here:
https://github.com/clojure/clojure/blob/master/src/clj/clojure/main.clj#L267
using this macro:
