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

             Summary: NullPointerException when trying to execute prepared 
statement using avatica
                 Key: CALCITE-1193
                 URL: https://issues.apache.org/jira/browse/CALCITE-1193
             Project: Calcite
          Issue Type: Bug
          Components: avatica
    Affects Versions: avatica-1.7.1
         Environment: Phoenix 4.7.0 and Phoenix 4.8.0-SNAPSHOT
            Reporter: Francis Chuang


To reproduce, set the phoenix query server to use JSON for serialization:

1. Create a table called {{my_table}} and seed it using SquirrelSQL:

{code}
CREATE TABLE my_table (k BIGINT PRIMARY KEY, v VARCHAR) TRANSACTIONAL=true

UPSERT INTO my_table VALUES (1,'A')

UPSERT INTO my_table VALUES (2,'B')

UPSERT INTO my_table VALUES (3,'C')

UPSERT INTO my_table VALUES (4,'D')
{code}

Send the following requests using curl:
{code}
C:\Users\user
λ curl localhost:8765 -XPOST --data '{"request": 
"openConnection","connectionId": "my-conn"}'

{"response":"openConnection","rpcMetadata":{"response":"rpcMetadata","serverAddress":"f826338-phoenix-server.f826338:8765"}}

Notice that the server throws a NPE when trying to execute the prepared 
statement.
