[eclipse-users] java visualisation client bug

The following program causes the Java visualisation client to report  
an "Unsupported operation exception" on my machine (an intel Mac  
running JDK 1.5 and eclipse 5.10 #82).

:- lib(ic).
:- lib(viewable).
:- lib(java_vc).

bad :-
	start_vc(_),
	viewable_create(view, [], array([flexible], any)),
	viewable_expand(view, 1, V).
	
The error occurs when it reaches the call to viewable_expand/4. It  
seems to occur no matter what visualisation I choose.

On the other hand, this code works:

good :-
	start_vc(_),
	viewable_create(view, [A], array([flexible], any)),
	viewable_expand(view, 1, V).

So it would appear to be something to do with attempting to extend an  
empty list.
