----------------------------------
Summary: ClassCastException when reading objects in Collection and
Map from ClientCache
Key: IGNITE-11458
URL: https://issues.apache.org/jira/browse/IGNITE-11458
Project: Ignite
Issue Type: Bug
Components: thin client
Environment: ignite-core.2.8.0
Reporter: Jinil Lee
There is a ClassCastException when reading objects in Collection or Map stored
in ClientCache while using thin client.
When deserializing a BinaryObject, I think that the Object in the Collection is
not being processed.
I made a patch and I think it works well with the my patch,
so please let me know if this is not a problem or if you have any other
solutions.
Below is the test code.
{code:java}
//Case 0. Object
ClientCache<String, Address> cache1 = igniteClient.getOrCreateCache("Object");
cache1.put("key", val);
System.out.println(cache1.get("key").getStreet());
//-----------------------
//Case 1. Collection
//-----------------------
ClientCache<String, List<Address>> cache2 =
igniteClient.getOrCreateCache("Collection");
List<Address> list = new ArrayList<>();
list.add(val);
cache2.put("key", list);
//OK!!!
System.out.println(cache2.get("key").get(0).getStreet());
//-----------------------
//Case 2. Map
//-----------------------
ClientCache<String, Map<String, Address>> cache3 =
igniteClient.getOrCreateCache("Map");
Map<String, Address> map = new HashMap<>();
map.put("key", val);
cache3.getAndPut("key", map);
//ClassCastException!!!
System.out.println(cache3.get("key").get("key").getStreet());
//-----------------------
//Case 3. Colection + Map
//-----------------------
ClientCache<String, List<Map<String, Address>>> cache4 =
igniteClient.getOrCreateCache("Collection_Map");
List<Map<String, Address>> mapList = new ArrayList<>();
mapList.add(map);
cache4.put("key", mapList);
//ClassCastException!!!
System.out.println(cache4.get("key").get(0).get("key").getStreet());
{code}
