          Issue Type: Bug
    Affects Versions: 2.8
            Reporter: Alex Serbin


When trying to create a simple cache with Cassandra store and have value persistence strategy POJO, the following exception occurs


{code:java}
Caused by: java.lang.NullPointerException: nullCaused by: java.lang.NullPointerException: null at org.apache.ignite.cache.store.cassandra.persistence.PojoField.calculatedField(PojoField.java:155) ~[ignite-cassandra-store-2.8.0.jar:2.8.0] at org.apache.ignite.cache.store.cassandra.persistence.PersistenceController.prepareLoadStatements(PersistenceController.java:311) ~[ignite-cassandra-store-2.8.0.jar:2.8.0] at org.apache.ignite.cache.store.cassandra.persistence.PersistenceController.<init>(PersistenceController.java:85) ~[ignite-cassandra-store-2.8.0.jar:2.8.0] at org.apache.ignite.cache.store.cassandra.CassandraCacheStore.<init>(CassandraCacheStore.java:106) ~[ignite-cassandra-store-2.8.0.jar:2.8.0] at org.apache.ignite.cache.store.cassandra.CassandraCacheStoreFactory.create(CassandraCacheStoreFactory.java:59) ~[ignite-cassandra-store-2.8.0.jar:2.8.0] at org.apache.ignite.cache.store.cassandra.CassandraCacheStoreFactory.create(CassandraCacheStoreFactory.java:34) ~[ignite-cassandra-store-2.8.0.jar:2.8.0] at org.apache.ignite.internal.processors.cache.GridCacheProcessor.createCacheContext(GridCacheProcessor.java:1199) ~[ignite-core-2.8.0.jar:2.8.0] at org.apache.ignite.internal.processors.cache.GridCacheProcessor.prepareCacheContext(GridCacheProcessor.java:1995) ~[ignite-core-2.8.0.jar:2.8.0] at org.apache.ignite.internal.processors.cache.GridCacheProcessor.lambda$null$6a5b31b9$1(GridCacheProcessor.java:1830) ~[ignite-core-2.8.0.jar:2.8.0] at org.apache.ignite.internal.processors.cache.GridCacheProcessor.lambda$prepareStartCaches$8(GridCacheProcessor.java:1754) ~[ignite-core-2.8.0.jar:2.8.0] at org.apache.ignite.internal.processors.cache.GridCacheProcessor.lambda$prepareStartCaches$926b6886$1(GridCacheProcessor.java:1827) ~[ignite-core-2.8.0.jar:2.8.0] at org.apache.ignite.internal.util.IgniteUtils.lambda$null$1(IgniteUtils.java:11138) ~[ignite-core-2.8.0.jar:2.8.0] at java.util.concurrent.FutureTask.run$$$capture(FutureTask.java:266) ~[na:1.8.0_181] at java.util.concurrent.FutureTask.run(FutureTask.java) ~[na:1.8.0_181] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) ~[na:1.8.0_181] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) ~[na:1.8.0_181] at java.lang.Thread.run(Thread.java:748) ~[na:1.8.0_181] {code}
It looks like that recent changes of IGNITE-1903 are leading to this issue, as we are starting to serialize cacheStoreFactory, which contains PojoFiled, which in its turn has transient field accessor. This leads to accessor being null after deserialization.

Works fine with Ignite 2.7.6.

Probably related to IGNITE-8500
