Bug#893359: jboss-xnio FTBFS with openjdk-9

[Markus Koschany]

I could solve one part of the build issues with Java 9 but I am stuck with

"/build/jboss-xnio-3.6.2/api/src/main/java/java/nio/channels/FileChannel.java:[19,1]
package exists in another module: java.base
"

I have read about the new --patch-modules option but I am not sure if
this is the right way. Renaming the package is probably the way forward.
However upstream is still working on Java 9 support and I don't want to
act prematurely. Let's see with what they will come up with. Hopefully
it happens before Buster freezes.
