I've inserted an issue in JIRA. I'll see what I can do today.
By the way, could somebody create a component for documentation in JIRA?

Subject: [Springframework-developer] Strange 'double' singleton bug
I'm not sure if this is a bug or not, it's certainly strange behaviour.
We had a singleton bean that was operating normally, but when we make
it implement ApplicationListener - we get _two_ instances of it
created. (Tested by simply putting a debug point in the constructor -
two separate beans are created)
Here's the config snippet:
<bean id=3D"macroManager"
class=3D"com.atlassian.renderer.macro.DefaultMacroManager">
<constructor-arg>
<ref local=3D"macroStateStore"/>
</constructor-arg>
<constructor-arg>
<list>
<ref local=3D"beanMacroLoader"/>
<ref local=3D"classpathMacroLoader"/>
</list>
</constructor-arg>
</bean>
Is this a known bug, a feature or am I not meant to use
ApplicationListener this way? (if it's a bug it's quite serious I'd
say)
I want to do it this way because another part of Confluence fires an
event to say that all setup has finished - and I want this bean to
listen for that event and further initialize itself.
I just guessed that in Spring I would just need to implement the
ApplicationListener interface and listen for events - if I need to do
anything else, let me know :)
Cheers,
Mike

Errr, I replied to the wrong email I guess ;-)
It was supposed to be a reply to the scheduling question from Mike CB

Mike,

Your approach seems to be perfectly OK. I've just tried to reproduce =
your issue but wasn't able to: I always get a single instance, no matter =
if implementing ApplicationListener or not. Could you double-check the =
effect, and possibly send a minimal test case that reproduces the =
problem?

I just tried to reproduce it with our code against CVS HEAD and can't replicate it. Against 1.0.1 I can replicate it every time though. Should I just assume it's fixed in Spring CVS HEAD and therefore will be fixed in the next release?

That's odd - I don't really know why this has changed since 1.0.1. Might = be worth tracking down the root cause: For example, log an exception = from the constructor of your class to see the instantiation stacktraces = (or use a debugger to see those stacktraces). On the other hand, it's = good that it seems to behave properly now rather than the other way = round...
