space " " produced in jsonencoder ?

[Yang]

if I do

writer = new SpecificDatumWriter<SpecificRecord>(schema);
encoder = EncoderFactory.get().jsonEncoder(schema, ostream);

writer.write(my_specific_record, encoder);
writer.write(my_specific_record.encoder);


it adds a space " " between the 2 records, I guess for separation.
is it possible to remove that? or changing that to "\n" is much better


Thanks
Yang
