Details:

I have just updated to Java 9 on my system (Debian testing/unstable).

With this update, the following test in ov-java.cc now fails for me


***** testif HAVE_JAVA; ! ismac () && usejava ("jvm") && usejava ("awt") &&
have_window_system ()
 frame = javaObject ("java.awt.Frame");
 frame.setResizable (true);
 assert (frame.isResizable ());
!!!!! test failed
[java] java.awt.AWTError: Assistive Technology not found:
org.GNOME.Accessibility.AtkWrapper


The reason for the failure is the call to java.awt.Frame:


>> frame = javaObject ("java.awt.Frame");
error: [java] java.awt.AWTError: Assistive Technology not found:
org.GNOME.Accessibility.AtkWrapper


But if I make the same call a second time, it works fine.

It's possible this is some Debian bug in transitioning to Java 9, but I
thought I'd report it and see if anyone else sees something similar.
