Question

I have code that basically does the following to read in properties that are added to json like e.g. ‘name’ and ‘ value’ in the follow JSON {"operation":"write-attribute","address":[{"subsystem":"web"},{"connector":"http"}],"name":"socket-binding","value":"jndi"}.
As the methods are generic, I can’s just rely on hardcoding name and value – other json strings could contain other properties that should be “caught”.

@JsonAnySetter
public void addAdditionalProperty(String key, Object value) {
    if (additionalProperties == null)
        additionalProperties = new HashMap<String, Object>();
    additionalProperties.put(key,value);
}

@SuppressWarnings("unused")
public void setAdditionalProperties(Map<String, Object> additionalProperties) {
    this.additionalProperties = additionalProperties;
}

@JsonAnyGetter
public Map<String,Object> getAdditionalProperties() {
    return this.additionalProperties;
}

@JsonIgnore
public String getName() {
   return (String) getProperty("name");
}

@JsonIgnore
public String getValue() {
   return (String) getProperty("value");
}

This code works well with Jackson 1.7.4, but fails in 1.9.3 where the additionalProperties are not set.
I fail to see if this is an intended change or if its is a regression.

If it is an intended change – does anyone know how to “fix” my code to work again?

Sounds like potential bug to me — easiest way to figure out is to either send question to user list, or file a Jira. I can do latter, see if I can see what happens.
