Class>>rename: only checks for an entry in the undeclared dictionary without considering that the weak references may not yet have been cleaned up.</div><div><br></div><div>I understand that this is not really a realistic real world use-case but it's still annoying for tests. My current workaround is a forced GC after *every* test in the entire suite (I use ClassFactoryForTestCase, so class names may be reused many times over). Luckily, the impact on runtime isn't too bad.</div><div><br></div><div>I'd appreciate it if this could be fixed. I'd be even more happy if I could be notified of the fix, so that I can remove the workaround again.</div></div></blockquote><div><br></div>Do you have ideas about where the bug lies?<br><div><br></div><br><blockquote type="cite"><div><div><br></div><div>Cheers,</div><div>Max</div></div></blockquote><br><div><span style="background-color: rgba(255, 255, 255, 0);"><br>_,,,^..^,,,_ (phone)</span></div></body></html>
