@JsonProperty(access = Access.READ_ONLY) does not work

Fails to work with 2.11.1

Test to reproduce the issue:

Bug.java

public class Bug {
    public static void main(String[] args) throws JsonProcessingException {
        ObjectMapper objectMapper = new ObjectMapper();
        Bean bean = new Bean();
        bean.setWorks("works");

        String json = objectMapper.writeValueAsString(bean);
        Bean newBean = objectMapper.readValue(json, Bean.class);
    }
}

Bean.java

import com.fasterxml.jackson.annotation.JsonProperty;

public class Bean {

    private String works;

    @JsonProperty(value = "t", access = JsonProperty.Access.READ_ONLY)
    public String getDoesntWork() {
        return "pleaseFixThisBug";
    }

    public String getWorks() {
        return works;
    }

    public void setWorks(String works) {
        this.works = works;
    }
}

Exception:

Exception in thread "main" com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "t" (class Bean), not marked as ignorable (one known property: "works"])

Expected behaviour: The property should only be serialized. However, it is being tried to deserialized.

This bug was supposed to be fixed with https://github.com/FasterXML/jackson-databind/issues/935

May I know when is the release of 2.12.0 planned?

@RakshithVP earlier I was hoping to get release out by September 2020, but that may slip – I still hope the first release candidate would be out in september.
