[Bluej-discuss] Hello all,

[Todd Whittaker]

Hello all,
 
I was putting together something for my students, and was walking
through some manual testing of a LinkedList implementation inside BlueJ.
I created an instance of the LinkedList object (type parameter provided
is irrelevant), and put it on the object bench.  This worked fine, and I
was able to use it to call the add method a few times. I then inspected
it and manually walked through the links to verify it was how I
expected. 
 
I then asked for a listIterator and put it on the object bench, and it
_looks_ like it creates an object, but then when I start trying to use
the iterator object BlueJ stops working fully. I'll execute a method on
the iterator and it just looks like it doesn't do anything. If I try and
call a method that expects a parameter, it then says something about " )
expected."

In addition, when I try to call methods on the original list now it
doesn't work. The menu works, and dialogues pop up prompting for
parameters, but the methods don't display return values, and again the "
) expected" error occurs when trying to pass parameters.
 
Another related problem seems to be that when creating objects in which
a type parameter is required, just ignoring the field and clicking on
the "Ok" button causes BlueJ to lock up.
 
Any suggestions?  This is under Windows XP SP2, BlueJ 2.1.2, JDK
1.5.0_05.  A quick check of BugZilla doesn't show anything related.
