After the Spring boot source code is compiled, it starts to report an error in debug mode

Question

I am trying to analyze the source code of spring boot.

I compiled the source code of spring boot 2.2.9 RELEASE, and no errors were reported. And use this version as a dependency of my test project, and the test project can be started normally in IDEA.

But when I start the project in debug mode in IDEA it produces an error.

I've looked at many resources online, but no one seems to have encountered a similar error.

I've tried multiple variations of this, but none of them seem to work. Any ideas?

Thanks in advance.
