I share the view of Dmitry.

We had a chat in #OpenJDK about one year ago how to solve this issue without having to designing a new namespace:
http://icedtea.classpath.org/wiki/New_os.arch_namespace_Architecture
I like the idea to re-use the existing namespace provided by the c/c++ compilers target name:
By using the compilers target name helps developers who cross compile jni code to select the right compiler for each platform they want to support.
