O. Reißig updated AVRO-1532:
----------------------------
Description:
*Actual behaviour:*
I have a field in my reflection-based schema like this:
{code}
@Nullable @AvroDefault("null")
public Long someField;
{code}
When removing this field, parsing the previous serialized blob yields
NullPointerException:
{noformat}
Caused by: java.lang.NullPointerException
