[jackson-user] Custom deserializer recursively calls `deserialize` method

['ilker cam' via jackson-user]

Hi,

I have a property which can be an integer or an object without any explicit 
`type` property. I tried to use JsonDeserialize annotation and provide a 
custom deserializer;

data class Report(val measures: List<IntOrMeasure>)

@JsonDeserialize(using=IntOrMeasureDeserializer::class)
sealed class IntOrMeasure {
    data class MeasureDefinition(val collection : 
DataMappingHttpService.RakamCollection, val name : String) : IntOrMeasure()
    data class MeasureId(val id : Int) : IntOrMeasure()
}

class IntOrMeasureDeserializer : JsonDeserializer<IntOrMeasure>() {
    override fun deserialize(p: JsonParser?, ctxt: DeserializationContext?): 
IntOrMeasure {
        return if(p!!.currentToken().isNumeric) {
            p.readValueAs(IntOrMeasure.MeasureId::class.java)
        } else {
            p.readValueAs(IntOrMeasure.MeasureDefinition::class.java)
        }
    }
}


p.readValueAs(IntOrMeasure.MeasureId::class.java) recursively calls 
deserialize again thus resulting with overflow.
Any insights are appreciated, thanks.
