Jessie KDE desktop doesn't communicate with Java

[Kevin McKinley <ntrfug@cox.net>]

I'm running Jessie KDE, updated through today with the following Java
installed:

openjdk-7-jre:amd64                   7u71-2.5.3-2
openjdk-7-jre-headless:amd64          7u71-2.5.3-2

I have the following gnome and libbonobo libraries installed:

libgnome-2-0:amd64                    2.32.1-5 
libgnome2-0:amd64                     2.32.1-5
libgnome2-bin                         2.32.1-5
libgnome2-common                      2.32.1-5
libgnomevfs2-0:amd64                  1:2.24.4-6+b1amd64
libgnomevfs2-common                   1:2.24.4-6
libgnomevfs2-extra:amd64              1:2.24.4-6+b1

libbonobo2-0:amd64                    2.32.1-3amd64
libbonobo2-common                     2.32.1-3

I run JMRI, the Java Model Railroad Interface. The KDE desktop doesn't
communicate properly with the JMRI. When JMRI asks the desktop to
open a text editor, the following error message is returned:

2014-12-22 15:12:22,688 trains.TrainPrintUtilities    WARN - desktop
edit not supported [AWT-EventQueue-0]

I'm not a programmer and I know nothing about Java or the KDE desktop
API.

Is there some additional package I should install or some configuration
I should do to make this work?

If there is a better place to ask this question I would appreciate a
pointer to it.
