SV: [aspectj-users] Weird problem with declare parent andjavax.naming.InitialContext

Hi

Ok, I'll give execution a try - Funny though, it works for all other Aspects
I have that advice different classes. I was starting to wonder it it had
something to do with the fact that InitialContext resides with Java's rt.jar

andjavax.naming.InitialContext

You can get into trouble using declare parents and call together.  You will
be better using 'execution' if you can.  The resolution sequence the VM
chooses means we may not get to see things in the order we would like and so
your itd may not get applied soon enough.  There are a few open bugs on this
in bugzilla.
