[platform-dev] Lookup-Problem between module suites

[Hermann Matthes]

Hello all,
I have the following problem using Lookup:

In a module of module suite "common" I defined a interface named
"IResourceManager".
In a module of module suite "resource", which includes all modules of
"common" I implemented that interface and added a service provider
annotation:
@ServiceProvider(service = IResourceManager.class)
In a module of module suite "server", which includes all modules of
"common" and "resource", I call
Lookup.getDefault().lookup(IResourceManager.class)
but it always returns null.

Whats my fault?

Thanks a lot in advance
Hermann
