OSGI and util.ServiceLoader

Hi all

I currently try to setup Arquilian with Felix embedded to test the OSGI
integration of Tamaya. I took some time, but so far  (not yet checked in) I
have a running version despite one issue:

It looks that loading of services using java.util.ServiceLoader does not
work anymore. Now before I dive even deeper into OSGI (I am aware of the
"OSGI way" of loading/acceessing "services") I would like to ask you guys
here on the list, if somebody can give me a hint:

1) Is there a way to get OSGI to work with the ServiceLoader logic, without
having to change code, e.g. by configuring the felix plugin accordingly? If
so, how?

2) Do you have other useful tipps how to get things working in both OSGI
and non OSGI worlds without having to add code deps in the Java code?

Thanks and have a nice evening
Anatole

No clean and really portable one.

A spi for service loading. This is what apache projects do most of the
time. Alternative is registration method OSGi and SE can use + a module
doing the registration with an Activator.
