Issues while deserializing exception/throwable using Jackson in Java

Question

I am facing issues while deserializing Exception and Throwable instances using Jackson (version 2.2.1). Consider the following snippet:

Answer 1

Try using polymorphism so that jackson deserializer knows what kind of Throwable to create:

/**
 * Jackson module to serialize / deserialize Throwable
 */
public class ThrowableModule extends SimpleModule {
  public ThrowableModule() {
    super("Throwable", new Version(1, 0, 0, null, null, null));
  }

  @Override
  public void setupModule(SetupContext context) {
    context.setMixInAnnotations(Throwable.class, ThrowableAnnotations.class);
  }

  /**
   * Add annotation to Throwable so that the class name is serialized with the instance data.
   */
  @JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = JsonTypeInfo.As.PROPERTY, property = "class")
  static abstract class ThrowableAnnotations {
  }
}
