Timothy A. Bish commented on ARTEMIS-4462:
------------------------------------------
This is most likely the same issue as was reported AMQCPP-692 where the CMS
client does not properly encode the strings and this causes the exception as
the decoding will fail when Artemis is converting from Openwire native to the
Artemis native CORE message. This comes down to a bug in the client that
hasn't been fixed and since the client is no longer maintained it is unlikely
to ever be fixed. I probably can sneak by in a 5.x broker so long as the
message contents aren't decoded broker side but will likely throw an exception
if that happened.

> Issue Type: Bug
> Affects Versions: 2.30.0
> Reporter: Liviu Citu
> Priority: Major
>
> When a text message non-UTF-8 (ISO-8859-15) containing special characters is
> sent from ActiveMQ CPP client to Artemis, an exception
> "java.io.UTFDataFormatException" is seen in Artemis server log.
> Although the exception is thrown as a warning, the message gets rejected by
> the server.

>
> This is a regression compared with ActiveMQ Classic which does not have this
> issue.
> Does Artemis support non-UTF-8 encoding? Do we need now to encode all
> messages to UTF-8 before sending them to the server? Similarly to decode them
> upon receiving?
> This will cause some problems on our end because:
> * we have many clients already using the ActiveMQ classic and migrating them
> to Artemis will cause issues when migrating KahaDB to Artemis because all the
> messages have to be encoded to UTF-8 otherwise they will not work in Artemis
> * encoding/decoding every message will impact the overall performance. We
> have applications handling thousands of messages every day and conversion of
> these messages will increase the time spent during communication with JMS
> broker
