Using SQL cache with javax cache api

[Dominik Przybysz]

Hi,
I created SQL cache, but sometimes I want to use it via javax.cache.api and
it doesn't work.

I created cache with SQL:

CREATE TABLE IF NOT EXISTS Person6 (
  id varchar primary key ,
  city_id int,
  name varchar,
  age int,
  company varchar
) WITH
"template=replicated,backups=1,wrap_key=false,value_type=java.util.HashMap,cache_name=Person6";

insert into PERSON6(ID, CITY_ID, NAME, AGE, COMPANY) values (
'1', 1, 'TEST', 20, 'Bla'
);

insert into PERSON6(ID, CITY_ID, NAME, AGE, COMPANY) values (
'2', 1, 'TEST2', 20, 'Bla 1'
);

Next I created client and fetching data with SqlFieldQuery works without
problems:

SqlFieldsQuery query = new SqlFieldsQuery("SELECT * from Person6");
FieldsQueryCursor<List<?>> cursor = cache.query(query);

but when I tried to query the cache with get:

IgniteCache<String, Object> cache = ignite.cache("Person6");
System.out.println("CacheSize: " + cache.size(CachePeekMode.PRIMARY));
System.out.println("1: " + cache.get("1"));

I received:

CacheSize: 2
1: null

To solve it I added withKeepBinary():

IgniteCache<String, Object> cache =
ignite.cache("Person6").withKeepBinary();

and then I received valid data:

CacheSize: 2
1: java.util.HashMap [idHash=660595570, hash=-1179353910, CITY_ID=1,
ID=null, NAME=TEST, AGE=20, COMPANY=Bla]

but now I cannot add HashMap to the cache:

Map<String, Object> value = new HashMap<>();
value.put("ID", uuid);
value.put("CITY_ID", 1);
value.put("NAME", "c");
value.put("AGE", 90);
value.put("COMPANY", "AAAAA");
cache. put(uuid, value);

throws:

Exception in thread "main" javax.cache.CacheException: class
org.apache.ignite.IgniteCheckedException: Unexpected binary object class
[type=class
org.apache.ignite.internal.processors.cacheobject.UserCacheObjectImpl]

and adding works only with objects created with BinaryObjectBuilder.

Is it expected behaviour for caches String->HashMap?
