Bug 330978

Description Francois Chouinard 2010-11-23 17:21:35 EST

An ArrayOutOfBoundsException occurs when zooming in/out of the CFV while the checkpoints are still building.

It looks like a thread synchronization issue in drawItemDataDurations(): the method gets a reference to the list of trace events and then goes over it in sequence. Apparently, a competing thread (the one that builds the checkpoints) tampers with the list at the same time :-(
