DNSJava based resolver does not properly handle multiple identical TXT/SPF
records
----------------------------------------------------------------------------------
Key: JSPF-43
URL: https://issues.apache.org/jira/browse/JSPF-43
Project: jSPF
Issue Type: Bug
Affects Versions: 0.9b4
Reporter: Stefano Bagnara
Assigned To: Stefano Bagnara
Fix For: 0.9.5
This is a bug in dnsjava 2.0.3.

==================================
I'm using dnsjava to create a server and I'm not able to add multiple TXT
or SPF records with the same content because dnsjava does check for
"contains" and the equals for the records will return true if they have the
same text value.
I think this is a big because AFAIK dns specification should let me to
publish a couple of TXT records with identical content and they have to be
read as 2 records and not a single record.
Some protocol, like SPF, return a different result if there is a single
record or if there are multiple records (even if they are identical).
I added to TXTBase the equals method to check for Identity and now it works
like expected:
---
// Make sure this never matches an equals.
public boolean equals(Object arg) {
return this == arg;
}
---
I have the problem both on the server side (while trying to publish a zone
with multiple records) and worst of all on the client side when reading a
response containing multiple records.
