> BinaryObject can't be reused as key between caches because it's
> actual implementation BinaryObjectImpl implements KeyCacheObject and
> due to the fact caches partition, which is not recalculated later.
> See org.apache.ignite.internal.processors.cache.GridCacheAffinityManager.partition:
> {code}
> if (key instanceof KeyCacheObject && ((KeyCacheObject)key).partition() != -1)
>             return ((KeyCacheObject)key).partition();
> {code}
> The issue can be reproduced with the following code:
> {code}
> public static void main(String[] args) throws IgniteException {
>         IgniteConfiguration cfg = new IgniteConfiguration();
>         cfg.setDiscoverySpi(new TcpDiscoverySpi().setIpFinder(new TcpDiscoveryVmIpFinder(true)));
>         Ignite ignite = Ignition.start(cfg);
>         CacheConfiguration<BinaryObject, BinaryObject> cfg1 = new
>             CacheConfiguration<>("Cache 1");
>         cfg1.setCacheMode(CacheMode.PARTITIONED);
>         cfg1.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
>         IgniteCache<BinaryObject, BinaryObject> cache1 =
>             ignite.getOrCreateCache(cfg1).withKeepBinary();
>         CacheConfiguration<BinaryObject, BinaryObject> cfg2 = new
>             CacheConfiguration<>("Cache 2");
>         cfg2.setCacheMode(CacheMode.REPLICATED);
>         cfg2.setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_SYNC);
>         IgniteCache<BinaryObject, BinaryObject> cache2 =
>             ignite.getOrCreateCache(cfg2);
>         BinaryObjectBuilder keyBuilder = ignite.binary().builder("keyType")
>                 .setField("F1", "V1").hashCode("V1".hashCode());
>         BinaryObjectBuilder valBuilder = ignite.binary().builder("valueType")
>                 .setField("F2", "V2")
>                 .setField("F3", "V3");
>         BinaryObject key = keyBuilder.build();
>         BinaryObject val = valBuilder.build();
>         cache1.put(key, val);
>         cache2.put(key, val); // error
>         System.out.println(cache1.get(key)); // error
>         System.out.println(cache2.get(key)); 
>     }
> {code}
