      How frequently does the bug occur?

      Always

      Description

      I'm migrating from realm-java to realm-kotlin and I've encountered issue similar to https://github.com/realm/realm-kotlin/issues/981.
      I think that issue is that my class have two generics requiring descendants of RealmObject. -I've added example of second class with this issue at the bottom, this one has only one RealmObject generic.
      Maybe issue is occuring, because type requirments are listed in "where" clouse?

      Error is:

      Unable to find source-code formatter for language: org. Available languages are: actionscript, ada, applescript, bash, c, c#, c++, cpp, css, erlang, go, groovy, haskell, html, java, javascript, js, json, lua, none, nyan, objc, perl, php, python, r, rainbow, ruby, scala, sh, sql, swift, visualbasic, xml, yaml
      Caused by: java.lang.RuntimeException: Exception while generating code for:

      In order, for functions: equals, hashCode, toString. When I override those error is following:

      Class signature is following:

      class OrderMediaAddRequester(
    realm: Realm,
    mobile2Service: Mobile2Service,
    context: Context,
    listener: Listener
) : FileUploadQueueRequester<OrderMediaAddQro, OrderMediaRealmObject, ResponseEnvelope<ArrayList<Void>>>(
    realm,
    mobile2Service,
    context,
    OrderMediaAddQro::class,
    OrderMediaRealmObject::class,
    listener
)

It's base class:
abstract class FileUploadQueueRequester<QueueObject, MediaObject, R>(
    realm: Realm,
    protected var mobile2Service: Mobile2Service,
    protected var context: Context,
    clazz: KClass<QueueObject>,
    private val mediaClazz: KClass<MediaObject>,
    listener: Listener
) : AbstractQueueRequester<QueueObject, R>(
    realm, clazz, listener, true
) where QueueObject : RealmObject,
        QueueObject : QueueRealmObject,
        QueueObject : FileUploadQueueObject,
        MediaObject : RealmObject,
        MediaObject : AbstractMedia 

And base-base class:
abstract class AbstractQueueRequester<Q, in Response>(
    protected val realm: Realm,
    protected val clazz: KClass<Q>,
    private val listener: Listener,
    val isItUploading: Boolean
) where Q : RealmObject, Q : QueueRealmObject

      In FileUploadQueueRequester signature is visible that QueueObject and MediaObject both must implement RealmObject.

      Second example class

      class CarrierTypesSyncer(
    realm: Realm,
    mobile2Service: Mobile2Service,
    listener: Listener
) : SingleInstanceMobile2ServiceSyncer<CarrierTypesSyncRealmObject, CarrierTypesResponse>(
    realm, mobile2Service, CarrierTypesSyncRealmObject::class, listener
)

Base class:
abstract class SingleInstanceMobile2ServiceSyncer<S, R : ResponseEnvelope<*>?>(
    realm: Realm,
    mobile2Service: Mobile2Service,
    clazz: KClass<S>,
    listener: Listener
) : PrimitiveMobile2ServiceSyncer<S, R>(
    realm, mobile2Service, clazz, listener
) where S : RealmObject, S : GetterRealmObject

abstract class PrimitiveMobile2ServiceSyncer<S, R : ResponseEnvelope<*>?>(
    realm: Realm,
    protected var mobile2Service: Mobile2Service,
    clazz: KClass<S>,
    listener: Listener
) : PrimitiveSyncer<S>(
    realm, clazz, listener
) where S : RealmObject, S : GetterRealmObject 

abstract class PrimitiveSyncer<S> internal constructor(
    protected var realm: Realm,
    protected val clazz: KClass<S>,
    private val listener: Listener
) where S : RealmObject, S : GetterRealmObject
