KotlinReflectionInternalError Data Class

Question

I received the following error when attempting to use a data class as a result type in a Retrofit service.

To be honest I'm not even sure what this error means and I haven't found many resources about it. The class description is fairly vague:

Signals that Kotlin reflection had reached an inconsistent state from which it cannot recover.

The only place that is using reflection is within Moshi, but I cannot figure out what is causing the issue.

Code

This is the data class:

data class AuthenticationResponse(
    @Json(name = "access_token) val accessToken: String,
    @Json(name = "refresh_token) val refreshToken: String,
    @Json(name = "user_id") val userId: String,
    val scope: String
)

The AuthenticationService:

interface AuthenticationService {

    @FormUrlEncoded
    @POST("oauth/token")
    fun credentials(
        @Field("username") username: String,
        @Field("password") password: String,
        @Field("scope") scope: String,
        @Field("grant_type") grantType: String = "password"
    ): Flowable<AuthenticationResponse>

    @FormUrlEncoded
    @POST("oauth/token")
    fun refreshToken(
        @Field("refresh_token") refreshToken: String,
        @Field("scope") scope: String,
        @Field("grant_type") grantType: String = "refresh_token"
    ): Flowable<AuthenticationResponse>

}

I am using Moshi as the JSON converter, and I have included the KotlinJsonAdapterFactory in the Moshi.Builder.

Update

I can reliably reproduce the error by attempting to create an AuthenticationResponse adapter using Moshi directly.

val moshi = Moshi.Builder().add(KotlinJsonAdapterFactory()).build()
val json = "{\"user_id\": 000000," +
        "\"access_token\": \"testAccessToken\"," +
        "\"expires_in\": 3600," +
        "\"token_type\": \"Bearer\"," +
        "\"refresh_token\": \"testRefreshToken\"," +
        "\"scope\": \"test\"}"

val adapter = moshi.adapter<AuthenticationResponse>(AuthenticationResponse::class.java)

val response = adapter.fromJson(json)

Timber.d("response=$response")

The code above fails with the same KotlinReflectionInternalError when attempting to create the adapter value.
