Kyle misunderstood what you were asking.
The debugger is simply reporting that it found the proper place to set the breakpoint. It resolved from a symbol to an address.
Nothing has actually happened. No exception was raised or caught. The breakpoint has not yet been hit. The debugger is just preparing things.

Ken
