Assuming these get deployed in order (which I will look at next)
Yes, they do.
it seems strange that the RegisterModuleCallback receives bootstrap-, jmx-, deployers- and profile-classloader, but not the aop-, stdio and, asynch-classloaders
It's not strange if you look into aop.xml in more details. ;-)
It's simply a matter of order + a small detail. :-)
For the order this is obvious -- aop, stdio and asynch are all deployed before the registry is intalled.
And the small detail is this
<install method="addModule">
<parameter><inject bean="bootstrap-classloader:0.0.0$MODULE"/></parameter>
</install>
which is why you also see bootstrap.
