Hi,

I've a problem with runtime weaving of an enterprise application leading to a hard crash of the java runtime. There is an error entry in the server log, telling that he is not able to load a transformed class (see attachement). I think it is a problem that can not be solved in minutes, therefore I tried to exclude the class from instrumentation and I realized I'm not able to configure aop this way.

I'm using the following typedef and binding to instrument my system:

<typedef name="system" expr="class(com.XXX.*) AND !class(com.XXX.YYY.Foobar)" />
<bind pointcut="call(public * $typedef{system}->*(..))">
   <before aspect="..." trace="..." />
</bind>

I'm aware that instrumenting the whole application is very expensive but I have to do some kind of runtime tracing and this is the only way I see. Is this the way I should reach my goal or did I understand the documentation wrong?

Thanks in advance 

Bernhard
