All, I have posted an update on JIRA regarding these issues (which are the same) and I would appreciated everyones on input on the suggested solutions. http://opensource.atlassian.com/projects/spring/browse/SPR-472 For those of you who are unware 1.1.1 conatined a nasty bug where proxy creation, with CGLIB, would restore any default state in the target object if your constructor set this state explicitly through method calls. I fixed this 1.1.2 although annoying the fix was only partial and this problem still shows up, but only when methods called by the constructor are unadvised. Rob |

Looks like we will get a solution to this problem at the CGLIB level.

i would muchy prefer a CGLIB solution. I've never been totally comfortable with workarounds in Spring. Can we defer the
resolution, adding a note? What's their timeframe?

Just had an e-mail from Chris. He informs me that this is much more
difficult than he first thought but he should be taking serious look at
in the next few days.
