Error when using JodaTime in Pact given parameter

[huehnerlady]

Hi,
I am currently trying to use an Object containing Jodatime as a parameter for the given part.

import au.com.dius.pact.consumer.dsl.PactBuilder
import au.com.dius.pact.consumer.junit5.PactConsumerTestExt
import au.com.dius.pact.core.model.annotations.Pact
import de.europace.privatkredit.kex.vorgaenge.web.HttpConfig
import org.joda.time.LocalDate

[...]

  @Pact(consumer = "CONSUMER", provider = "PROVIDER")
  fun jodaTime(builder: PactBuilder) = builder
      .given("joda time as parameter", "testClass", TestClass(LocalDate.now()))
      .expectsToReceiveHttpInteraction("test") { httpBuilder ->
        httpBuilder
            .withRequest { httpRequestBuilder ->
              httpRequestBuilder
                  .path("/test")
                  .method("GET")
                  .header(CONTENT_TYPE, "application/json")
            }
            .willRespondWith { httpResponseBuilder ->
              httpResponseBuilder
                  .status(200)
            }
      }
      .toPact()

unfortunately I then get the error:

java.lang.IllegalAccessException: class kotlin.reflect.jvm.internal.calls.CallerImpl$FieldGetter cannot access a member of class org.joda.time.LocalDate with modifiers "private final"
kotlin.reflect.full.IllegalCallableAccessException: java.lang.IllegalAccessException: class kotlin.reflect.jvm.internal.calls.CallerImpl$FieldGetter cannot access a member of class org.joda.time.LocalDate with modifiers "private final"
	at kotlin.reflect.jvm.internal.KCallableImpl.call

Can you please fix this?
