Does Eclipse have a way to break when a variable changes values? If not, is there some crafty workaround that provides similar functionality. This would be helpful in general, but my specific short-term goal is to track down the point at which a variable becomes null since my program is crashing with a NullPointerException.

Nevermind, I finally found the answer in the Eclipse help menu. It turns out that in the "Variables" view, you can right click on a variable and select "Toggle Watchpoint." This will create a breakpoint that breaks when variable is accessed and/or modified. You can modify your newly created watchpoint in the "Breakpoints" view.
