Avro schema for nested arrays doesn't work

[Alex Kroifer]

Avro schema for nested arrays definition doesn't parse:

Schema:

{"type": "array", "items": {"name": "Rec1", "type": "record", "fields" : [
       {"type": "array", "items": {"name": "Rec2", "type":"record", "fields"
: [
                   {"name": "Scalar", "type": "string"}]}}]}}

Result:

No field name:
{"type":"array","items":{"name":"Rec2","type":"record","fields":[{"name":"Scalar","type":"string"}]}}
org.apache.avro.SchemaParseException: No field name:
{"type":"array","items":{"name":"Rec2","type":"record","fields":[{"name":"Scalar","type":"string"}]}}
        at org.apache.avro.Schema.getRequiredText(Schema.java:981)
        at org.apache.avro.Schema.parse(Schema.java:907)
        at org.apache.avro.Schema.parse(Schema.java:934)
        at org.apache.avro.Schema.parse(Schema.java:813)

What's wrong?

Thank you in advance,
Alex.
