Describe the bug
I am using Spring Shell to create a cli tool, the library works fine when run from the jar, however when compiled to a native binary and ran it throws a NullPointerException.
I have added the client-java-spring-aot-integrations dependency but it doesn't seem to have resolved anything, and I am also required to add the following to reflect-config.json otherwise I get a different error.

{
"name": "io.kubernetes.client.openapi.models.",
"unsafeAllocated": true
}
]When running as native it errors after Kubectl.get(...) is invoked:
