Vladimir Sitnikov commented on CONFIGURATION-596:
-------------------------------------------------
I've just double-checked and it looks like we do not use regular listeners
either.
{quote}If you are interested, you can create a patch against this class which
implements lazy initialization of the underlying COWList.{quote}
Do you mean 1.x branch?
{quote}I am not sure whether there will be another release for Configuration
1.x,{quote}
Any reasons for that?
{quote}I would propose focusing on current trunk development.{quote}
When a stable release is expected?
> Allow event listener Collections to be lazily created in event.EventSource

> It turns out every instance of {{AbstractConfiguration}} creates a couple of
> {{CopyOnWriteAraryLists}} for {{event.EventSource}}.
> In our usage patterns in most of the cases the lists are not used.
> Can the lists be lazy-initialized? (that is created on the first addListener
> request)
