How do you debug a series of Aspect in eclipse?

I've got a chain of aspects that are being executed in some cases but not in others. The stack typically looks something like this w/o giving an context information. There doesn't appear to be any logging that I can enable either. Thanks for any help on this.

From stackoverflow CodePolice

• You can step through aspects in a debugger if you've installed the AspectJ Development Tools (AJDT), a plugin for eclipse.
