Jari Louvem commented on AVRO-3980:
-----------------------------------
[~opwvhk] Thank you for your answer.
My doubt is about the existing encoded data. In case we change the method to
encode/decode, it will break the compatibility with these already encoded
(using BinaryEncoder) data as it won't be decoded by this BinaryMessageDecoder.
Is there a way to workaround this issue?

> Project: Apache Avro
> Issue Type: Bug
> Components: java, logical types
> Affects Versions: 1.11.3
> Reporter: Jari Louvem
> Priority: Critical
>
> After we upgraded Avro library and avro-maven-plugin from version 1.11.1 to
> 1.11.3 and
> we started to get the error "cannot read collections larger than 2147483639
> items in java library".
>
> This error is generated by SystemLimitException.checkMaxCollectionLength.
> The data that we are trying to deserialize (using avro 1.11.3) was serealized
> using avro 1.11.1.
> The object that we are trying to deserealize is:
> {
> "name": "statuses",
> "type": {
> "type": "array",
> "items": "com.entity.avro.StatusAvro"
> }
> }
> {
> "name": "statuses",
> "type": {
> "type": "array",
> "items": {
> "name": "StatusAvro",
> "type": "record",
> "namespace": "com.entity.avro",
> "fields": [
> {
> "name": "status",
> "type": [
> "null",
> "string"
> ]
> },
> {
> "name": "reason",
> "type": [
> "null",
> "string"
> ]
> },
> {
> "name": "validFor",
> "type": "com.entity.avro.ValidForAvro"
> }
> ]
> }
> }
> }
> {
> "name": "validFor",
> "type": {
> "name": "ValidForAvro",
> "type": "record",
> "namespace": "com.entity.avro",
> "fields": [
> {
> "name": "start",
> "type": "long"
> },
> {
> "name": "end",
> "type": "long"
> }
> ]
> }
> }
> This is an example of the objects listed above:
> "statuses": [
> {
> "status": "INIT",
> "reason": "Final_New_Reason",
> "validFor": {
> "start": "2020-01-30T11:45:00.839Z",
> "end": "2030-01-23T06:58:21.563Z"
> }
> }
> ]
> The problem is that the array has only one item as shown above, so why is it
> throwing an error of the collection is too long?
