Java 9 is currently not an option for libbluray. I looked at the
changes required for Java 9 couple of months ago. Even if we fix build
time issues, new packaging model of JVM 9 prevents loading the .jar
file. There are also several unresolved runtime issues.

It should be possible to compile the .jar file with JDK 9 if sources
are compiled against older Java rt libraries. This requires older JRE
(but not JDK) for build and runtime.

The second patch won't build or run with Java < 9.

We can either patch FocusEvent and CausedFocusEvent to work in both
versions, or add new version of BDFramePeer.java for Java 9. If we add
new version, resulting .jar file won't work with JRE < 9. But I don't
know if it will be an issue if we need to split the .jar anyway ...
