TypeMappedAnnotation.getValue(int,boolean,boolean) burns a lot of CPU, 2x total CPU usage on process after upgrade from 5.1 to 5.2

See original GitHub issue

Affects: 5.2 Type: Bug

SpringFramework 5.2 has a regression in CPU performance when dealing with RequestParameters with default values in combination with having a Filter that looks at the HttpServletRequest & HttpServletResponse (AccessLogging). The impact on CPU is massive when upgrading from 5.1 to 5.2.

I replicated the behaviour here https://github.com/jensim/spring-boot-compare-22-21

@jensim in light of the fix for #24970, could you please try out a 5.2.6 snapshot build to see if that improves the situation for you?

Looking forward to your feedback!

Its still a noticeable regression over 5.1, if you are looking for it.

We are indeed considering other ways to improve the performance of our annotation processing.
