Re: How to support ServiceLoader.load(class, class.ClassLoader)

Hi Huan,

When you're calling ServiceLoader.load(Class, ClassLoader) you are already
explicitly specifying an actual classloader. So you should not need to use
Aries SPI-Fly at all, but just need to ensure that the classloader provided
is the right one. SPI Fly (and the OSGi ServiceLoader Mediator spec) is
about handling the implicit classloader used with ServiceLoader.load(Class).

If for some reason you the code that calls ServiceLoader.load(Class,
ClassLoader) is not passing the right classloader then I think the best way
would be to fix that code.
I guess SPI Fly could support a scenario like this but it would mean that
existing actual code is changed, rather then additonal code inserted. I'm
not too sure if that is really the best thing to do, but if there is a need
for it then I think it could be considered as an addition, if someone
proposes a patch...

Cheers,

David
