I'm seeing a weird error that I cannot figure out. Suppose I have this:

abstract class MyService : BuildService<BuildServiceParameters.None> {
  abstract val myProperty: NamedDomainObjectContainer<MyType>
}

abstract class MyExtension constructor(val service: Provider<MyService>) {
  val myProperty
    get() = service.get().myProperty
}

override fun apply(project: Project) {
  val service = project.gradle.sharedServices.registerIfAbsent(SERVICE_NAME, MyService::class.java) {}
  val extension = project.extensions.create<MyExtension>(EXTENSION_NAME, service)
  
  extension.myProperty.register(...)
}

I'm seeing a weird

ClassCastException

being emitted from this code:

Caused by: java.lang.ClassCastException: MyService$Inject cannot be cast to MyService

The stacktrace seems to be pointing to the

service.get()

call in

MyExtension.myProperty

. Any ideas wrt what is going on?

it's probably from a different classloader
