Hi Tom,
hopefully you can enlight a java newbie :)
In javax/imageio/ImageReader.java you change the following for example
protected List progressListeners = new ArrayList();
to
protected List progressListeners = null;
The java doc says:
progressListeners:
A List of currently registered IIOReadProgressListeners, initialized by
default to null, which is synonymous with an empty List.
My problem is here:
protected void processImageComplete()
{
Iterator it = progressListeners.iterator();
in the same file.
I get an NPE on this since progressListeners is initialized to null, not
to an empty List, to null.
This prevents me to run the swing Demo in 2D mode.
I changed the above initializer to:
protected List progressListeners = new ArrayList(0);
now i can run the demo fine again.
So, am I missing an initialization of this progressListeners elsewhere?
Or is the initializing to null wrong?
Thanks,
Andreas
