Error deserializing object with list of maps

[oharaandrew314]

In Klaxon 2.1.14, the following test fails with the following exception.

    @Test
    fun objectWithListOfMaps() {
        val mapper = Klaxon()
        data class Data(val data: List<Map<String, String>>)

        val data = Data(listOf(mapOf("name" to "john")))
        val json = mapper.toJsonString(data)
        Assert.assertThat(mapper.parse<Data>(json), CoreMatchers.equalTo(data))
    }

java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl cannot be cast to java.lang.Class

However, this test does pass. Perhaps Klaxon doesn't like the nested generics.

    @Test
    fun objectWithListOfObjectsWithMaps() {
        val mapper = Klaxon()
        data class Row(val row: Map<String, String>)
        data class Data(val rows: List<Row>)

        val data = Data(listOf(Row(mapOf("name" to "john"))))
        val json = mapper.toJsonString(data)
        Assert.assertThat(mapper.parse<Data>(json), CoreMatchers.equalTo(data))
    }
