[jira] [Created] (IGNITE-11282) NullPointerException if transaction enabled and using byte[] for key/value

---------------------------------

             Summary: NullPointerException if transaction enabled and using byte[] for key/value
                 Key: IGNITE-11282
                 URL: https://issues.apache.org/jira/browse/IGNITE-11282
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 2.7
            Reporter: Courtney
         Attachments: Screen Shot 2019-02-10 at 15.02.19.png

I have debugged this and found the problem is because of hashCode comparison failure. You can see in the screenshot below. 
{code:java}
txMap == null ? null : txMap.get(key)
{code}
this will fail to get the entry but they the key is in fact in the map, it's the only entry and if a proper array comparison is done e.g. using `Arrays.equals` as shown in the eval window then the key would match. !Screen Shot 2019-02-10 at 15.02.19.png!

If running without `-ea` then the exception is
{code:java}
