Description

When there are multiple records in a FlowFile, and there is a field in these records of type Decimal ("type": "bytes", "logicalType": "decimal") and the FlowFile is converted to Avro with AvroRecordSetWriter's property "Schema Write Strategy" set to "Do not write schema", then when this avro file is parsed with AvroReader (Schema access strategy set to "Use 'Schema Text' Property" and schema explicitly provided) some decimal values get assigned random values.
Template attached to reproduce the issue.
