> An NPE occurs when Phoenix attempts to retrieve a char array from an index.
> Retrieving other columns in the table is unaffected. Example below:
> {code:sql}
> 0: jdbc:phoenix:xxxxxx> CREATE TABLE IF NOT EXISTS TEST.TEST("testInt"
> INTEGER, "testCharArray" CHAR(3)[], CONSTRAINT "test_pk" PRIMARY
> KEY("testInt")) DEFAULT_COLUMN_FAMILY='T';
> No rows affected (2.223 seconds)
> 0: jdbc:phoenix:xxxxxx> UPSERT INTO TEST.TEST VALUES (5, ARRAY['aaa', 'bbb']);
> 1 row affected (0.165 seconds)
> 0: jdbc:phoenix:xxxxxx> SELECT "testCharArray" FROM TEST.TEST;
> +---------------+
> | testCharArray |
> +---------------+
> | ['aaa', 'bbb'] |
> +---------------+
> 1 row selected (0.183 seconds)
> 0: jdbc:phoenix:xxxxxx> CREATE INDEX IF NOT EXISTS TEST_INDEX ON TEST.TEST
> ("testInt") INCLUDE ("testCharArray");
> 1 row affected (10.331 seconds)
