Follow-up Comment #1:

Maybe we should abandon all Java-dialogs, instead of trying to fix and
maintain unused code. There are two concurrent implementations of dialogs
(Java and QT). The documentation still mentions only Java:

https://www.gnu.org/software/octave/doc/v4.0.1/Dialog-Box-Functions.html#Dialog-Box-Functions

The concurrency is visible in 

scripts/gui/private/message_dialog.m,

where first always the QT variant is tried, thereafter the Java variant. Thus
I think no one has ever really seen the Java variant before, as QT works
naturally with the GUI.

The java variant is implemented in

scripts/java/org/octave/*.java

the QT variant in

libinterp/corefcn/octave-link.{h/cc}

The only pro for the Java-variant is, that it is able to print some TeX
symbols

https://www.gnu.org/software/octave/doc/v4.0.1/Which-TeX-symbols-are-implemented-in-dialog-functions_003f.html

This doesn't apply for the QT-variant, but for me this feature has never been
accessible before and it is a minor victim for clarifying the code a lot.

As I don't get negative respone, I will remove the Java-variant with changes
to the calling code and documentation.
