Re: [aspectj-users] Crosscutting method's executions

[Wes Isberg <wes@xxxxxxxxxxxxxx>]

Yes, you can do bytecode weaving in 1.1.  This is documented in 
the FAQ and in the 1.1 distribution README, online at 
  
http://dev.eclipse.org/viewcvs/indextech.cgi/~checkout~/aspectj-home/README-11.html

However, weaving Sun libraries would violate their license. Rather
than tracing system method executions, consider tracing method calls 
to system methods from your code (and avoid tracing calls from
the advice).  But the API's you mentioned (wait, etc.) would not
be traced when called from system code.

As a newbie, you'll find a lot of questions answered in the FAQ, 
the documentation, and the README's, but bear in mind that the 
docs are in transition from 1.0 to 1.1.

Have fun!
