Re: [aspectj-users] LTW fail hard/fast options (for testing)

[Andy Clement <andrew.clement@xxxxxxxxx>]

Right now perhaps the option you have here is -XmessageHandlerClass
which is supplied the classname of a type implementing IMessageHandler
- so you can then do what you want for any message that comes out.  I
guess you could use the type name of the THROW class if you wish,
likely to be something like "org.aspectj.bridge.IMessageHandler$1" (as
a workaround for it being non 'top-level' at the moment).

I think I raised a bugzilla already for another approach I was
thinking of, where you annotated the advice/pointcut with expectations
(I expect it to match X number of times) and errors will be thrown if
the expectation isn't met.  This is more straightforward with compile
time weaving though as you know when that has finished - it isn't so
obvious in LTW when it has reached the point where the expectation
should have been met. (there may still be more types to be loaded).

cheers,
Andy
