Need space between "*" and filename.

In general, all these things look quite good. They all share one major 
problem, though, I think: event filtering. According to my handy-dandy 
table of possible filters for events, ExceptionEvent, Method*Event, and 
SingleStepEvent can all be filtered using: CountFilter, 
ThreadOnlyFilter, ClassOnlyFilter, ClassMatchFilter, ClassExcludeFilter, 
LocationOnlyFilter, and InstanceOnlyFilter. [SingleStep can use one 
more, but that would not be part of this event class, I think.]

All I think you need to do is add an Object to the constructors of all 
of these that can be returned from getParameters. [Hmm. I don't think 
InstanceOnlyFilter is right, either. It should be able to use 
getParameter(Object.class) I think.]

The only other comment is that ExceptionEvents cannot be filtered by 
their caught locations: this location is only used for reporting it to 
the deubgger. So just drop all of that extra stuff.
