Hi @cuiweixie,

Congratulations on submitting your first PR for the Spring Framework! 👍

Please note, however, that MethodDelegate resides in the org.springframework.cglib.reflect package, which is our fork of the CGLIB project.

In addition, the following is our policy on such code.

Please refrain from modifying classes under org.springframework.asm, org.springframework.cglib, and org.springframework.objenesis. Those include repackaged forks of the third-party libraries ASM, CGLIB, and Objenesis. Any refactoring to those classes should take place upstream in the originating repository. The Spring Framework will then pick up the changes when syncing with official updates of the forked third-party libraries.

In light of the above, I am going to close this PR.

Thanks anyway
