Hi, I'm trying out the JDK 9 EA with Jigsaw.
I created two modules, A and B, which are required by module C. Modules A and B contain a non-exported package with the same name. After compiling each module separately I start module C and get a java.lang.reflect.LayerInstantiationException saying that modules A and B contain a package with the same name. In light of this behaviour I have two questions. - Is it correct to say that for a simple Java SE application to work with this configuration the only solution, in the realm of what will be provided with the GA version of JDK 9, is through the concept of layers of modules? - In that case will there be some sort of out-of-the box functionality to have this scenario work or will I have to write some non-trivial code to manage these layers? In other words, I have to use different versions of the same library in a Java SE application. Since Jigsaw is approaching I thought I could wait for it instead of learning and having to deal with OSGi. But from what I see by using only Jigsaw I won't be able to satisfy this requirement. At least not without writing some non-trivial code that I'm afraid is above my skill level. Cheers, Karl
