Re: [aspectj-users] overlapping pointcuts and a compiler bug

[chris colombo <chriscol002@xxxxxxxxx>]

I restarted eclipse and everything worked fine...

however i still have this question:
 
if i have the following two advises:

before(): (execution (* *.*())){} before(): (execution (* *.atest())){}

can i somehow decide their precedence during runtime?
