           This packet is a bit tricky on the debug adaptor side since there
           is no "clear exception breakpoints" packet. Exception breakpoints
           are set by sending a "setExceptionBreakpoints" packet with zero or
           more exception filters. If exception breakpoints have been set
           before, any existing breakpoints must remain set, and any new
           breakpoints must be created, and any breakpoints that were in
           previous requests and are not in the current request must be
           removed. This exception tests this setting and clearing and makes
           sure things happen correctly. It doesn't test hitting breakpoints
           and the functionality of each breakpoint, like 'conditions' and
           x'hitCondition' settings.
