javah deprecated?

[Johan Vos]

I filed a bug (https://bugs.openjdk.java.net/browse/JDK-8192806) and I am
looking into it.

It seems a bit weird to me that the java.lang.Character and java.net.IDN
header files are needed. I'll remove them and see where it fails.
But if they are needed (and they probably are), it won't be easy to
generate them with javac -h as that requires the source code instead of the
classfiles. That would require access to the java.lang.Character and
java.net.IDN java source code in OpenJDK, from within OpenJFX.
