[Octave-bug-tracker] [bug #53305] usejava ("awt") may fail on macOS

[Rik]

Follow-up Comment #1, bug #53305 (project octave):

The actual code that Octave executes is in usejava.m


    case "awt"
      try
        dum = methods ("java.awt.Frame");
        retval = ! javaMethod ("isHeadless", "java.awt.GraphicsEnvironment");
      end_try_catch


@Sebastian: Just to help narrow it down, can you log in to the macOS buildbot,
start octave interactively, and then try each command individually to see
which one is causing the dialog box?

The next question to google or search on StackOverflow for is how to correctly
detect the features of a JVM.  If this isn't the right way, fine, we can
change it.  But I don't know why it appears to work on other platforms, except
possibly that they never have Apple's version of Java and always have a true
version from Sun/Oracle.
