> Key: ARTEMIS-2268
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2268
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Reporter: Leo Provido
> Priority: Major
>
> We were trying out some existing tests with the latest build of Artemis
> (2.7.0-SNAPSHOT - as of 27-Feb-2019) and we encountered an exception thrown.
> When this occurs, our consumer is replying to a received message (i.e.
> sending a message to another queue on the same broker). The exception
> message that is shown in the Artemis log is also reported back via the AMQP
> client library.
> Below shows the exception and stack trace found in artemis-service.out.log.

> throw new ProtonException("Expected Symbol type but
> found encoding: " + encodingCode);
> }
> }
> From the exception message (org.apache.qpid.proton.ProtonException: Expected
> Symbol type but found encoding: -95), encoding code has symbol -95 which does
> not match any of the switch cases SYM8, SYM32 and NULL.
> Note that this issue does not occur in Artemis 2.6.3 and 2.6.4 but does occur
> in the latest Artemis build (2.7.0-SNAPSHOT - as of 27-Feb-2019).
