> {code}
> && ((partitionStateSerializer == null && ((Snapshot) obj).getPartitionStateSerializer() == null)
> || partitionStateSerializer.equals(((Snapshot) obj).getPartitionStateSerializer()))
> && ((partitionStateSerializerConfigSnapshot == null && ((Snapshot) obj).getPartitionStateSerializerConfigSnapshot() == null)
> || partitionStateSerializerConfigSnapshot.equals(((Snapshot) obj).getPartitionStateSerializerConfigSnapshot()));
> {code}
> The null check for partitionStateSerializer / partitionStateSerializerConfigSnapshot is in combination with another clause.
> This may lead to NPE in the partitionStateSerializer.equals() call.
