Gary Russell opened SPR-17319 and commented
Currently, the validate() method parses the parameter annotations on every call.
It should be possible to cache the results and only parse on the first call.

This applies to several method argument resolvers in the web space as well. A consistent caching strategy for validation metadata across all of them sounds worthwhile.

A recent related change #26787 - reusing this ValidationAnnotationUtils should go along nicely here.
