Hi,<br>
<br>
I think this is an old bug, presumably since
ProtoObject was introduced (and presumably
because ObjectTracer was used in<br>
the process).<br>
<br>
If you ask Class for its subclasses (or if
you inspect it) you see that ObjectTracer
class is listed along with<br>
ProtoObject class, although ObjectTracer's
superclass is ProtoObject.<br>
This can lead to some funny bugs if you try
to write some hierarchy traversing code.<br>
<br>
Cheers,<br>
Florin<br>

Hi Eliot,<br>
<br>
I thought the fix was obvious - we just need to evaluate
"Class removeSubclass: ObjectTracer class" - so other
than pointing out the bug, I am not sure what else I
should do.<br>

<div><br>
</div>
<div>well what one could do is</div>
<div>a) create an update</div>
<div>b) create e.g. a Kernel package containing a postscript
that says Class removeSubclass: ObjectTracer class</div>
<div>c) create another update</div>
<div><br>
</div>
<div>I *think* that forces the load of the package with the
"Class removeSubclass: ObjectTracer class" postscript.
Bert, am I right?</div>
