NIFI-6369: This closes #3560. Updated JSON Readers to convert String values to
Date/Time/Timestamp objects when appropriate according to the schema and the
configured pattern
NIFI-6939: Fix to WriteJsonRecord to deal with date/time/timestamp when no
format is explicitly set
> ValidateRecord routes JSON records to 'invalid' when validating a timestamp,
> even if format is valid

> Key: NIFI-6369
> URL: https://issues.apache.org/jira/browse/NIFI-6369
> Project: Apache NiFi
> Issue Type: Bug

> If a JSON Reader (either JsonPath or JsonTree reader) is used with
> ValidateRecord and the schema indicates that a field is a timestamp (e.g.,
> {"name": "timestamp", "type": \{"type": "long",
> "logicalType":"timestamp-millis"}}
> ) with the JSON having a value like "2019/06/10 12:00:00Z" and a format of
> "yyyy/MM/dd HH:mm:ss'Z'" The processor considers this invalid, even when
> setting "strict type checking" to "false".
> This appears to be due to the way that ValidateRecord calls
> RecordReader.nextReader() - it calls it "reader.nextRecord( /* coerce types
> **/* false, /* drop unknown types **/* false)"
> When this is called, the Record Reader checks the 'coerce types' flag and
> determines that it should not coerce the string "2019/06/10 12:00:00Z" into a
> timestamp. However, for any date/time/timestamp fields, if the value is a
> String and it matches the configured pattern, the Record Readers should go
> ahead and convert the value into the appropriate java.sql.Date,
> java.sql.Time, java.sql.Timestamp object because that's clearly the intent of
> the schema and formatting being applied.
