             Summary: Affinity function must check for null keys
                 Key: IGNITE-3263
                 URL: https://issues.apache.org/jira/browse/IGNITE-3263
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 1.6
            Reporter: Denis Magda
             Fix For: 1.7


AffinityFunction implementations must check for {{null}} keys and through 
meaningful exceptions in such a cases.

As an example the following code trows NPE since the keys is not validated

{code}
Cache<AffinityKey&lt;String>, Person> personCache = ..;
personCache.get(new AffinityKey<>(key, affKey)); // returns value
personCache.get(new AffinityKey<>(key)); // throws NPE

Exception in thread "main" java.lang.NullPointerException
