Garrett Rooney commented on ABDERA-46:
--------------------------------------
Shouldn't the fact that a WeakHashMap is used keep it from causing a memory
leak?
I can certainly see the thread safety bit being an issue though, but that seems
pretty simple to fix.
(Note, I'm assuming we're talking about the ExtensionFactoryMap's wrappers Map,
although I could be totally missing the point here...)

> Okay, am trying to reconstruct this from memory as I thought we had a filed a
> bug on it months agao when we found it...
> If you use the same Factory from multiple threads it maintains a map of
> extension namespaces. When you create a new element it accesses this map and
> if an addition is going the reader can get caught traversing it forever.
> (HashMap is not thread safe).
> This map also keeps all extensions it ever sees, which can lead to a memory
> leak if you use the default factory a lot -- say, with hundreds of thousands
> of extensions in my case.
