Flow Encryption Commands can truncate floating point numbers

The encrypt-config.sh command from NiFi Toolkit, as well as the set-sensitive-properties-key and set-sensitive-properties-algorithm commands use a shared nifi-flow-encryptor module to read and write the JSON flow configuration.

The JSON Flow Encryptor reads JSON elements and handles values according to parsed token type information. When the parser encounters a token type of FLOAT, the Encryptor calls JsonParser.getFloatValue(). However, the parsed value could contain a number of greater precision, such as a double. In this situation, the JSON Parser truncates the double precision to float precision. This can impact serialization of position coordinates for Processors in the Flow Configuration.
