UpdateMapper drops numeric keys in Maps

[RamThirupathy]

Numeric Bson Ids are dropped when using findAndModify method in org.springframework.data.mongodb.core.MongoTemplate.

Ex:

public class Foo {
 private Map<String, String> map;
 
 private Map<String, String> getMap() {
   return map;
 }

 private void setMap(Map<String, String> map) {
   this.map = map
  }
}

@Test
public void test() {
    Foo foo = new Foo();
    mongoTemplate.save(foo);
    Update update = new Update().set("map.601218778970110001827396", "testing");
    druryIssue = mongoTemplate.findAndModify(new Query(Criteria.where("_id").is(foo.getId())), update,
          new FindAndModifyOptions().returnNew(true),  Foo.class);
    System.out.println(druryIssue.map);
}

Foo is saved us

{
    "_id" : ObjectId("6023ff93defc2460cc3c4a26"),
    "_class" : "com.test.Foo",
    "map" : "testing"//it should have been "map.601218778970110001827396":"testing"
}

and resulting in exception

Note: This is working when we directly using Java Mongo driver instead of spring-data-mongodb.
spring-data-mongodb version is: 1.10.18.RELEASE

Thanks for reporting. We'll look into this.

Note that the 1.x line of Spring Data MongoDB is out of maintenance since late 2019.
