JsonBuilder StackOverflowError

A StackOverflowError in JsonBuilder can occur when there is a circular reference in the object being serialized. This means that an object contains a reference to itself, either directly or indirectly through other objects.

To fix this issue, you can try using a custom serializer that handles circular references. You can also modify your object model to remove the circular reference.

If you are using the Jackson library, you can use the @JsonIdentityInfo annotation to handle circular references. This annotation tells Jackson to use a unique identifier for each object instead of serializing the object again.

For example, you can add the following annotation to your class:

@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
public class MyClass {
    private int id;
    private MyClass parent;
    
    // getters and setters
}

This tells Jackson to use the "id" property as the unique identifier for each object. When serializing the object, Jackson will only include the "id" property and not serialize the entire object again.

Alternatively, you can use a library like GSON or JSON-Lib that has built-in support for handling circular references. These libraries can automatically detect circular references and serialize them correctly.
