Description

Values are compared using CacheEntryPredicateContainsValue predicate, this predicate call F.eq(thisVal, cacheVal) to compare, which gives false for two instances of arrays with the same content.

Reproducer:

IgniteCache<Object, Object> cache = startGrid().getOrCreateCache(DEFAULT_CACHE_NAME);
Object val = new byte[] {1};
cache.put(1, val);
assertTrue(cache.replace(1, val, val));
