Looking at the sources, it seems like my analysis was completely wrong. And I
can't even remember how I came to that conclusion :) (I remember seeing a
"bool" somewhere, but can't find it anymore.. :/)

In fact, asm's ClassWriter has an init method accepting int:

    public ClassWriter(final int flags) {
        [..]
    }

And also the documentation says it's there:

    http://asm.ow2.org/asm32/javadoc/user/org/objectweb/asm/ClassWriter.html

So, I can't really say how to fix this. Maybe the "<init>(I)V" in the
stacktrace helps? (not being a Javist, I could only infer that "I" means
integer, but don't know what "V" means)

The only difference I can see is in the class init methods. Compare the one
above with:

public class DebuggingClassWriter extends ClassWriter {
    public DebuggingClassWriter(int flags) {
        super(flags);
    }
[..]
}

See, the only difference is the "final" keyword in ClassWriter. I don't know if
this could be related to the bug.
