Hi Charles,
I haven't heard from you on this issue and I was curious on how your
research is going.
I did some research on it myself, since I had similar issues in the past. I
can't tell if the root cause in your case and mine is the same. For my case
I came up to the conclusion that the issue is that "sometimes reflection
does not work on cglib proxies". I also blogged about it. You can have a
look at

Hi,
For the moment, I continue to use @Transaction annotation in the DAO
layer instead of the service layer. That means that I deploy two
bundles but keeping @Transaction in one to avoid this issue.
This is also how spring use this annotation in their Spring DM
examples (see GreenPage example) !! So they are aware that there is an
issue.
Kind regards,
