I would like to know if/why I should upgrade CGLib 2.2.2 to Version 3.0. I am using CGLib with the latest versions of Hibernate/Spring/Mockito and Java 7.
I can not find release notes or upgrade directions for this version anywhere on the web.

Yes you should migrate to CGLib 3.1 because it can correctly generate stack map frame and deal with Java 7 bytecode.
Update
The following issues were all addressed by CGLib 3.1
We're using EasyMock and switched to a custom version of CGLIB 3. We switched because code coverage with EclEmma/JaCoCo/Sonar would no longer work. It was more or less a drop in replacement (apart from updating POMs). Unfortunately
CGLIB 3 is not (yet) in Maven CentralCGLIB 3 has a blocker bug https://sourceforge.net/tracker/?func=detail&aid=3601081&group_id=56933&atid=482368 so we had to build a custom version and deployed it to our in-house Nexus
So if you don't currently have any issues like code coverage no longer working I would not switch.

cglib3 is now in maven central. The bug mentioned above however is still open for the time being – Gelin Luo Nov 08 '13 at 01:23

Amazing, unfortunately it says it's fixed in 1.0. I don't know if that means 3.1. – Philippe Marschall Jan 03 '14 at 10:02
