java - 5.2 中的 spring AnnotationUtils 不再搜索父类？

Question

我在 springframework 中发现了 5.1.x 和 5.2.x 之间的差异，我试图弄清楚这是我所做的事情还是回归。

我有一个 bean 扫描器，它将在上下文中搜索已弃用的内容，并且在 spring 5.2.x 中，它似乎不再扫描父类中的注释。我要么做错了什么，要么存在错误，要么需要更新 javadoc。

这似乎是一个回归，目前计划在 5.2.2 中修复 https://github.com/spring-projects/spring-framework/issues/23929
