I'll take another pass through the Javadoc on the changes in AVRO-753 and
AVRO-769.
I may have missed some details.
JsonEncoder's class Javadoc has this info:
"
/** An {@link Encoder} for Avro's JSON data encoding.
* </p>
* Construct using {@link EncoderFactory}.
* </p>
* JsonEncoder buffers output, and data may not appear on the output
* until {@link Encoder#flush()} is called.
* </p>
* JsonEncoder is not thread-safe.
* */
"
It has no public constructors.
JsonDecoder however is missing the equivalent.
