I haven't been seeing this, it's new to me. What JDK and OS are you using?
Earlier versions had some issues with inner classes that were resolved.
If you could turn on debugging of generated classes it would be
useful. Enable logging for your component class name and it will be
produced at level debug. The output is a description of all the
changes that occured to the class file as part of the transformation
and can be quite useful.
