Subject: [PATCH] Fix null assignment to non-nullable field

Update `BeanRegistrationCodeFragments` package-private constructor
to set `codeFragments` to `this` rather than `null`. The field
is never actually read by `DefaultBeanRegistrationCodeFragments` since
all methods are overridden.

Closes gh-28578
