Infinispan Hotrod translator fails depending on size of data returned.

I have a table with more than 5000 rows.

When I issue following query:
{code:sql}
SELECT IntKey FROM BQT1.LargeA WHERE Intkey<4095
{code}
correct results are returned.
| 0 |
| 1 |
| ... |
| 4094 |

When I issue:
{code:sql}
SELECT IntKey FROM BQT1.LargeA WHERE Intkey<4096
{code}
following exception occurs and no results are returned:

{code}

Please note, that this is not affected only by number of rows, also by number of columns. So we're hitting a size limit on whole result set (influence of data type size has not been confirmed).

This affects also DELETE operation, as selection is part of the operation.
