Using a simple test:
public class pathtest {
    public static void main(String[] args) throws Exception {
        System.out.println("library path: " +
System.getProperty("java.library.path"));
    }
}

Only LD_LIBRARY_PATH was affecting the output, and setting a
- -Djava.library.path has overriden it. Including the defaults of JDK!
That's probably another problem, maybe it should also add LDPATH from
the VM's env file?
And related to https://bugs.gentoo.org/show_bug.cgi?id=125563 add some
sane defaults like /lib:/usr/lib ...

That doesn't matter, package.env is our artifact, not everything there
is usually used in the real env :)

If someone sets LD_LIBRARY_PATH then he expects it to be used
everywhere, why force another var for java.

I'm for LD_LIBRARY_PATH. Or as compromise, append both LD_ and JAVA_
variables. That way one can set additional paths for java without
affecting everything else.
