Investigate removal of KParameter class generation

[jamesnetherton]

For the SQL extension I had to work around a problem with a NoClassDefFoundError for a Kotlin class: KParameter.

I never got to the bottom of what was causing it. KParameter is only referenced in a few places which I added substitutions for.

It would be good to see if the problem can be resolved and the workaround removed.

What is bringing Kotlin into the mix in the first place?

It's an optional dependency of Spring. But because there is some Kotlin class usage in spring-core & spring-bean, it gets detected during the native image build. Hence the substitutions and workaround.
