Performance degradation for after Spring 3 [SPR-9972]

[spring-projects-issues]

Ray opened SPR-9972 and commented

We found after upgrade to Spring 3.1.1, AOP behavior is changed and more overhead is added.
I found method org.springframework.util.ClassUtils.getMostSpecificMethod(Method, Class<?>) is changed and will call Class.getDeclaredMethods instead of Class.getMethod, which will be more expensive.

Hi Ray, thanks for the report. This issue should actually already be fixed as of 3.1.3 and 3.2 RC1 with the resolution of #14435. See 49294c9 for details.

Give one of those versions a shot and let us know how it goes!
