------------------------------------

             Summary: 4-byte Unicode message from JMS to STOMP will be corrupted
                 Key: AMQ-8398
                 URL: https://issues.apache.org/jira/browse/AMQ-8398
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker, STOMP, Transport
    Affects Versions: 5.16.3
            Reporter: Simon Lundstrom


When sending a message from:
JMS producer to STOMP consumer
or
STOMP producer to JMS consumer
which contains a 4-byte unicode code points e.g. https://unicode-table.com/en/1F5A4/ there is a corruption of the message.
In the JMS to STOMP case the code point gets converted to:
{{ef bf bd ef bf bd}} when it should be {{f0 9f 96 a4}}.
and in the STOMP to JMS case the JMS client throws an exception:
{code}
Exception in thread "main" javax.jms.JMSException: java.io.UTFDataFormatException

        at testkonsument.App.main(App.java:42)
Caused by: java.io.UTFDataFormatException

        at org.apache.activemq.command.ActiveMQTextMessage.decodeContent(ActiveMQTextMessage.java:101)
        ... 3 more
{code}

Using 4-byte unicode points
from STOMP to STOMP
or
from JMS to JMS
is not a problem, both works and does not corrupt the code point.

Note that 2- or 3-byte Unicode code points does NOT get corrupted, even if the same message includes a 4-byte Unicode code point.
