John McClean updated AVRO-1754:
-------------------------------
Description:
When decoding null, the ValidatingDecoder does not call the underlying
'decodeNull' method. The result is that the next field decoded causes an
exception.
For example, if this json
{quote}
/{"a":null,"b":"bar"}
{quote}
is decoded with this schema
{quote}
{
"name": "foo",
"type": "record",
"fields": [
{ "name": "a", "type": ["null", "string"] },
{ "name": "b", "type": "string" }
]
}
{quote}
it throws an exception with the message "Invalid operation. Expected: String
got Null". This happens when 'b' is being decoded. I'll attach a patch.
