Hm, this seems to be very interesting. I have a hierarchy of three 
aspects where the cflow pointcut is defined in the base class of this 
hierarchy and I decompiled all three classfiles after weaving. Noone 
contains a field definition for the cflow. Seems to me that my case 
might be indeed a different one. Could any other change to the weaver 
code possibly created this problem? I am so puzzled because an older 
build worked fine...
