Hi,
I am pretty sure that the Felix framework does nothing around annotations.
According to the JavaDoc of the RetentionPolicy annotation, only a
retention policy of "RUNTIME" ensures an annotation is available at
runtime. A policy of COMPILE will put it into the class file but the VM
need not retain it at runtime (this seems to be the default, too).
Regards
Felix
