Wildcard Generic Fields class cast exception #216

Closed daivanov closed 7 years ago

Issue reported by Ryan Bergman in Google Groups:

Hello, I have some beans that are generated by JAX-B. I want to populate them all with some junk for some tests. So far I love the PODAM library but I am running into one snag I'm not sure how to get around. Some beans have some windcard types like this:

@XmlElementRef(name = "reportedLocation", namespace = "http://api.foo.com/v3", type = JAXBElement.class)
protected List<JAXBElement<? extends ReportedLocation>> reportedLocations;

When PODAM hits this I get this exception:

java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.WildcardTypeImpl cannot be cast to java.lang.Class at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:722) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojoInternal(PodamFactoryImpl.java:568) at uk.co.jemos.podam.api.PodamFactoryImpl.manufactureAttributeValue(PodamFactoryImpl.java:946) at uk.co.jemos.podam.api.PodamFactoryImpl.fillCollection(PodamFactoryImpl.java:1214) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:618) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:801) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojoInternal(PodamFactoryImpl.java:568) at uk.co.jemos.podam.api.PodamFactoryImpl.manufactureAttributeValue(PodamFactoryImpl.java:946) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:739) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojoInternal(PodamFactoryImpl.java:568) at uk.co.jemos.podam.api.PodamFactoryImpl.manufactureAttributeValue(PodamFactoryImpl.java:946) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:739) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojoInternal(PodamFactoryImpl.java:568) at uk.co.jemos.podam.api.PodamFactoryImpl.manufactureAttributeValue(PodamFactoryImpl.java:946) at uk.co.jemos.podam.api.PodamFactoryImpl.fillCollection(PodamFactoryImpl.java:1214) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:618) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:801) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojoInternal(PodamFactoryImpl.java:568) at uk.co.jemos.podam.api.PodamFactoryImpl.manufactureAttributeValue(PodamFactoryImpl.java:946) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:739) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojoInternal(PodamFactoryImpl.java:568) at uk.co.jemos.podam.api.PodamFactoryImpl.manufactureAttributeValue(PodamFactoryImpl.java:946) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:739) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojoInternal(PodamFactoryImpl.java:568) at uk.co.jemos.podam.api.PodamFactoryImpl.manufactureAttributeValue(PodamFactoryImpl.java:946) at uk.co.jemos.podam.api.PodamFactoryImpl.fillCollection(PodamFactoryImpl.java:1214) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:618) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:801) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojoInternal(PodamFactoryImpl.java:568) at uk.co.jemos.podam.api.PodamFactoryImpl.manufactureAttributeValue(PodamFactoryImpl.java:946) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:739) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojoInternal(PodamFactoryImpl.java:568) at uk.co.jemos.podam.api.PodamFactoryImpl.manufactureAttributeValue(PodamFactoryImpl.java:946) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:739) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojoInternal(PodamFactoryImpl.java:568) at uk.co.jemos.podam.api.PodamFactoryImpl.manufactureAttributeValue(PodamFactoryImpl.java:946) at uk.co.jemos.podam.api.PodamFactoryImpl.populatePojoInternal(PodamFactoryImpl.java:739) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojoInternal(PodamFactoryImpl.java:568) at uk.co.jemos.podam.api.PodamFactoryImpl.manufacturePojo(PodamFactoryImpl.java:173) at integration.SerializationCompatibilityTest.generate(SerializationCompatibilityTest.java:27)

Any idea on this? again, this is a property of another object up the object graph so it's not obvious how to register something to get around it.

Also It might be nice to have a brute force option so you could tell PODAM that if it hits a snag on one property to just keep going and do whatever else it can.

Thanks for a great library! Ryan

Fixed in Podam 7.0.0. Could be verified from a snapshot https://oss.sonatype.org/content/repositories/snapshots/uk/co/jemos/podam/podam/7.0.0-SNAPSHOT/podam-7.0.0-20161008.075918-2.jar

That worked, thank you very much for such a quick response.

Thank you for the verification. I want to add couple of things before releasing 7.0.0.
