Could capabilities be used to represent dependencies between native
libraries?

'cause that is the way it was designed in Java? System.loadLibrary is
typically called from some class' static initializer to define the
native methods of the class. System.loadLibrary calls
ClassLoader.findLibrary to request advice in locating the native
library. For bundle class loaders, this can then provide the location
of the native library mentioned in the bundle's Bundle-NativeCode
manifest header.
In your example, since a class in bundle 1 has a static initializer
calling System.loadLibrary("1"), then that code needs to first trigger
a class loader from bundle 2 where that class' static initializer
calls System.loadLibrary("2"). This will then make sure lib2.so is
loaded before lib1.so.
In general, the native code support in Java is really only useful for
loading JNI native libraries. How the dependencies of the JNI native
libraries are met is not addressed.

Subject: [equinox-dev] looking up binaries
Sent by: [email protected]
------------------------------------------------------------------------
Hey,
I have a situation where the binaries for my application are spread
across multiple bundles and those libraries depend on each others. For
example, I have bundle1 that carries lib1.so and I have bundle2 that
carries lib2.so, and bundle1 depends on bundle2. When I try to load
lib1.so if lib2.so has not yet been loaded, then the loading of lib1
will fail.
Is there a fundamental reason why we loading of the libraries could
mimic the loading of classes?
Thx
Pascal
