That looks like userland code; this list is about GNU Linux-libre, one
of the kernels of the GNU system. I believe you meant to write to the
gnu-linux-libre at nongnu.org list instead, which discusses issues having
to do with 100% Free GNU/Linux distros, so I'm copying that list,
including a complete (quoted) copy of your post.

I suggest checking whether these classes and all of their dependencies
are present in IcedTea, or in the source portion of OpenJDK. If they
are, then the classes can be used under the Free Software license that
governs the Java code in these projects. Otherwise, you'd be better off
refraining from using the Java class that relies on them, or using a
modified version that does not depend on the classes that may turn out
to be non-Free, and that might be removed from future releases of the
