Hi Dave,
yes this is tracked in https://issues.apache.org/jira/browse/JOHNZON-142
and 77
long story short setting final fields was not intended and lead to
inconsistencies so this behavior has been dropped.
if you need the previous behavior and are sure it is intended you can get
it back using:
WithFinalMap o = new MapperBuilder()
.setAccessMode(new FieldAccessMode(true, true) {
@Override
protected Map<String, Field> fields(Class<?> clazz,
boolean includeFinalFields) {
return super.fields(clazz, true);
}
})
.build().readObject("{\"m\":{\"A\":\"a\"}}", WithFinalMap.class);
That said i wouldnt recommand you to do it and maybe use the constructor
rather than this old hack
