Responsible-Changed-Why:
    I'm taking this.
    Sorry it took me so long to look at it.

State-Changed-Why:
    foo/bar/bing/MySharedClass.java is missing the
    correct `package' statement.
    If you add the package statement, this works.

>Description:
	The following test code doesn't work (at least, on x86 Linux).
I thought foo.bar.bing.MySharedClass is supposed to get picked out of foo-bar.so.
>How-To-Repeat:
	Extract this test case and run `make'
