^-- had to both unroll the method, and add JVMStatic

I reproduced your problem
@JVMStatic is not required
the problem comes from using an expression body (= instead of {})
now the question is, why???

[Lucas]

Maybe it's the SpringApplication.run() return type. Main expects a Unit.

[nfrankel]

it’s not maybe
it’s exactly that 🙂

I was sure that both removing the expression body and adding @JVMStatic were required.

Tested without.

[nfrankel]

no
this is just because by using an expression body, you changed the signature of the main method
