Runtime exception every time classes are reloaded

Description of the bug

Every time hot-reload is triggered, I get the following exception:

It looks like an issue in the Spring hotswap plugin. Do you have the full stacktrace reporting the original cause of the exception? Perhaps the plugin is calling some Spring API that has been changed
