> When a binary type is registered during first insertion without use of BinaryObject, then fields of type {{Map}} are registered as {{Object}}-s.
> It leads to inconvenience in further usage of this type over {{BinaryObject}} interface.
> The following code results in an exception:
> {code:java}
> public static void main(String[] args) {
>     Ignite ignite = Ignition.start("config/ignite.xml");
>     IgniteCache<Integer, ExamplePojo> cache = ignite.getOrCreateCache("cache");
>     cache.put(1, new ExamplePojo());
>     BinaryObject val = cache.<Integer, BinaryObject>withKeepBinary().get(1);
>     Map<Integer, String> map = val.field("map");
>     map.put(1, "1");
>     BinaryObjectBuilder bldr = val.toBuilder();
>     bldr.setField("map", map);
>     bldr.build(); // Throws exception.
> }
> static class ExamplePojo {
>     Map<Integer, String> map = new HashMap<>();
> }
> {code}
> Stacktrace:
> {noformat}
> Exception in thread "main" class org.apache.ignite.binary.BinaryObjectException: Wrong value has been set [typeName=binary.BinaryObjectMapExample$ExamplePojo, fieldName=map, fieldType=Object, assignedValueType=Map]
