--------------------------------------
Any idea when this will be fixed?
> 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
> Assignee: Jean-Baptiste Onofré
> Priority: Major
>
> 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
> org.apache.activemq.util.JMSExceptionSupport.create(JMSExceptionSupport.java:72)
> at
> org.apache.activemq.command.ActiveMQTextMessage.decodeContent(ActiveMQTextMessage.java:104)
> at
> org.apache.activemq.command.ActiveMQTextMessage.getText(ActiveMQTextMessage.java:84)
> at testkonsument.App.JMS(App.java:86)
> at testkonsument.App.main(App.java:42)
> Caused by: java.io.UTFDataFormatException
> at
> org.apache.activemq.util.MarshallingSupport.convertUTF8WithBuf(MarshallingSupport.java:389)
> at
> org.apache.activemq.util.MarshallingSupport.readUTF8(MarshallingSupport.java:358)
> 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- (e.g. https://unicode-table.com/en/00F6/) or 3-byte (e.g.
> https://unicode-table.com/en/2614/) Unicode code points does NOT get
> corrupted, even if the same message includes a 4-byte Unicode code point.
