使用 MockK 创建模拟时遇到问题。我已经尝试过使用没有 Kotlin 1.3 的 MockK 的 kotlin 1.2.* 版本，但它也没有帮助。
我该如何解决这个问题？这是因为 OpenJDK 11 的原因吗？
爪哇版：

历史客户：
interface AccountHistoryClient
测试：
@ExtendWith(MockKExtension::class)
internal class ReactiveLoadTransactionsHandlerTest {
@MockK
lateinit var historyClient: historyClient
@InjectMockKs
lateinit var handler: Handler
@Test
fun handle() {
}
}
当我运行此测试时，我收到此错误
