Reject not sent when repeating group out of order (OpenFIX)

This is a failing OpenFIX test. Here's what OpenFIX has to say about it:

===========
This tests your ability to handle a message with a repeating group whose fields are out of order. We will send you an Allocation message with two repeating groups, each of which has its fields in the incorrect order.

Expected flow:

• Send Reject (session-level) referencing the repeating group with the incorrect field ordering
• Increment inbound MsgSeqNum
• Generate an "error" condition in test output

The details of these session-level tests can be found in the FIX 4.3 Specification, Volume 2.
===========

I get this message in the error log, but no reject message:

13:45:51,000 ERROR [SocketConnectorIoProcessor-0.0] mina.initiator.InitiatorIoHa
ndler (AbstractIoHandler.java:117) - Invalid message: Repeating group 78 is out
of order: first field should be 79, but was 80.

Here is the message they send:
