Spring WebTestClientExtensions.expectBody doesn't work for generic types

Since WebTestClientExtensions.expectBody uses plain Class instead of ParameterizedTypeReference, it cannot correctly deserialize generic types.

package net.example

import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.web.bind.annotation.GetMapping
import org.springframework.web.bind.annotation.RestController

@SpringBootApplication
class ExampleApplication

@RestController
class ExampleController {
    @GetMapping("example")
    fun index(): ExampleWrapper<ExampleData> = ExampleWrapper(ExampleData("EXAMPLE"))
}

data class ExampleWrapper<T>(val payload: T)

data class ExampleData(val string: String)

package net.example

import org.junit.jupiter.api.Assertions
import org.junit.jupiter.api.Test
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.autoconfigure.web.reactive.WebFluxTest
import org.springframework.test.web.reactive.server.WebTestClient
import org.springframework.test.web.reactive.server.expectBody

@WebFluxTest(ExampleController::class)
class ExampleControllerTest @Autowired constructor(
    private val webClient: WebTestClient
) {
    @Test
    fun test() {
        webClient.get()
            .uri("/example")
            .exchange()
            .expectBody<ExampleWrapper<ExampleData>>()
            .consumeWith {
                Assertions.assertEquals(ExampleData::class, it.responseBody!!.payload::class)
            }
    }
}

java.lang.AssertionError: 
Expected :class net.example.ExampleData
Actual   :class java.util.LinkedHashMap
