This error is occurred while using JsonObject(GSON Library) in cache value if I used String instead of JsonObject then operation perform successfully.
Error which I have get while inserting data in cache:

Cache Configuration:
CacheConfiguration<String, JsonObject> cacheConfig = new CacheConfiguration<>();
cacheConfig.setName("CACHE_NAME");
cacheConfig.setReadThrough(true);
cacheConfig.setBackups(2);
cacheConfig.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
cacheConfig.setWriteThrough(true);
cacheConfig.setCacheStoreFactory(FactoryBuilder.factoryOf(ObjectLoader.class));
IgniteCache<String, JsonObject> cache = ignite.getOrCreateCache(cacheConfig);
Operations:
1.create JsonObject (use GSON library)
2.set cache loader to the given cache which used for persistent store
3.insert data into the cache from ignite client-side
4.observe the issue
The problem is that JsonObject has members field of type LinkedTreeMap, and Ignite BinaryMarshaller, which is default one, deserializes it into a LinkedHashMap for some reason.
To avoid it you can use a different marshaller, for example, OptimizedMarshaller.
UPD:
Turns out, if you configure OptimizedMarshaller, then only puts and gets from cache will work fine. But if you try to get(...) some field of the deserialized representation of JsonObject, for example, then JVM will crash.
The reason is that LinkedTreeMap has the following writeReplace() method:
private Object writeReplace() throws ObjectStreamException {
return new LinkedHashMap(this);
}
So, if you serialize it, and after that deserialize, then you will get an instance of LinkedHashMap instead of LinkedTreeMap. So, BinaryMarshaller is doing nothing wrong.
Summary:
Looks like you shouldn't put JsonObjects into cache. It doesn't implement Serializable, so the authors didn't think about serializing it. I think, you will have to replace JsonObject with JSON strings.
