Default Unknown type is not LinkedHashMap

[Kai-W]

The documentation to Unknonw Types states that the default is LinkedHashMap. Aktually a JsonObject is returned. JsonObject used to extend LinkedHashMap in 4.19.1 but since 4.19.2 implements Map

String json = "{\"test\":{}}";
ReadOptions options = new ReadOptionsBuilder().build();
System.out.println(json);
System.out.println("getUnknownTypeClass: "+ options.getUnknownTypeClass());
Object objects = JsonIo.toObjects(json,options, Object.class);
System.out.println(objects);

Results in

{"test":{}}
getUnknownTypeClass: null
JsonObject(id:-1, type:java.util.Map, target:null, line:0, col:0, size:1)

with unknownTypeClass(LinkedHashMap.class)

{"test":{}}
getUnknownTypeClass: class java.util.LinkedHashMap
{test={}}

the same behaivor is with an unknown @type and failOnUnknownType(false)
