SnapFeedbackPolicy resource management bug? [message #189573] Wed, 27 July 2005 14:27 Go to next message

Using the SnapFeedbackPolicy, I just found out that there seems to be a
major resource leak in the color management. The policy keeps calling
FigureUtilities.mixColors in getLocalBackgroundColor(), and does not
dispose of these colors. Using the SWT resource tracking tool Sleak, I
had a 30.000 colors after about ten minutes of editing. After copying
SnapFeedbackPolicy and taking care of the disposal (in
FadeIn.pointFigure and FadeIn.paint) the leak seems to be gone. Am I
missing something here or should I file a bug report?

I think we should fix this even though Color's not a resource, because a
reference count is being maintained and would affect palette-based displays.
It seems the undisposed colors aren't being garbage-collected either.
