Hello Guilhem,
just curious - what do you want to achieve? Do you want just "reset"
singletons state or actually really reload "new" class?
if answer is "reset", your solution might work but I don't think that
it's best way - in this case it would be more transparent to have
something like reset() method.
if you want to actually reload that class, it would not work, because
you are reusing already created AbstractResource instance. If it is for
development purposes, you might want to use jrebel, see [1].
I guess I just need to better understand what are you trying to do and
why, so if you can, please provide more details.
Thanks!
Pavel
