"Receiver class does not define or inherit an implementation" with RestAssured 4.3.0

Question

When running the following WebTestClient test

    @Test
    fun `test accepted response`() {
        standaloneSetup(SapKontraktEndpointV1())

        given()
            .body(
                "{}", ObjectMapperType.JACKSON_2
            )
            .contentType(ContentType.JSON)
        .`when`()
            .post("/api/v1/kontrakt/erstellen")
        .then()
            .statusCode(202)
    }

Then the following error occurs:

java.lang.AbstractMethodError: Receiver class io.restassured.internal.mapping.ObjectMapperSerializationContextImpl does not define or inherit an implementation of the resolved method 'abstract void setProperty(java.lang.String, java.lang.Object)' of interface groovy.lang.GroovyObject.

With 4.2.0 the test run is successful.

Answer 1

In my case it seems to be a bug in 4.3.0, because with 4.2.0 tests run fine.
