Getting exception Unknown MsgType: 0 not supported

Hi,
We have a rfa publisher application written in Java running on Linux. We are trying to troubleshoot some exceptions that we are seeing in the logs.
We are using testclient to try and reproduce the issue. The exception we are seeing is the following -
2023-11-28 08:41:04.416 Caught internal exception [com.reuters.rfa.omm.OMMException: Unknown MsgType: 0 not supported]
in thread [rsslNamespace::localProviderSession Session EventQueueGroup]
com.reuters.rfa.internal.rwf.RwfDecoder.unsafeDecodeMsg(Unknown Source)
com.reuters.rfa.internal.rwf.RwfDecoder.decodeMsg(Unknown Source)
com.reuters.rfa.internal.rwf.RwfMsgParsed.<init>(Unknown Source)
{5}
This repeats multiple times
Followed by -
Received OMMCmd ERROR EVENT for id: 13842 Trying to publish item with inactive token.:com.reuters.rfa.session.omm.OMMItemCmd@2a56b204
We can only produce it when disconnecting (ctrl-c) testclient and reconnecting again to the publisher.
Do you know what either of these exceptions might mean?
Thanks,
John

Hello @john.bailie
Which version of RFA Java API that encounters the issue? The latest versions of the API are 8.2.3.L1 and 7.8.1.L1. If you are not using the latest version, please migrate to the latest version to avoid all known issues.
If the issue still persists on the latest version, please give us the following information:
- The Java version
- The Linux platform detail
- The replication steps with XML trace logs when the problem occurs
- Can you replicate the issue with RFA Java OMM StarterProvider_Interactive example?

Hi,
We are using RFA Version: 8.0.0.E1.all.
Do you have a link where I can download the latest version from?
Thanks,

Checking through the release notes for the RFA API
I did see the following -
---------------------------------------
rfaj8.0.0.E2.all
---------------------------------------
RFAJAVA-498; Interactive provider application throws an
"OMMException: Unknown MsgType:0 not supported" when it repeatedly receives
subscription/unsubscription requests.
This has been fixed.
(CaseId: 04032572)Is it possible to do a minor upgrade rather than a major one?
An upgrade to the latest version might require additional development work and testing.
Thanks,
