(285/308) 1875 - Mac OS X Support plugin exception with Java 9-ea+157

jEdit 5.3.0
Plugin: Mac OS X Support 1.3
Platform: macOS 10.12.3
Java version: 9-ea+157

Just wanted to give you a little headstart regarding Java 9 bugfixes.

Several exceptions are showing up during startup. Those are all related to com.apple.eawt being unavailable. Unfortunately, the implementation of those classes did also change so starting the JVM with `--add-exports java.desktop/com.apple.eawt=ALL-UNNAMED` option does not fix the problem.

I took the easy way out in my application and got rid of the special OS X handling for now. Starting with Java 9, such support should be handled by http://download.java.net/java/jdk9/docs/api/java/awt/Desktop.html and http://download.java.net/java/jdk9/docs/api/java/awt/desktop/package-summary.html

I'm unaware of any way to support both Java 9 and Java >= 8 at the same time.

Similar exceptions are thrown for other setXyzHandler methods. There are also some NPEs but those seem to have the same root cause.
