Timothy Bish commented on AMQ-5629:
-----------------------------------

Recommend you create a unit test or enhance one of the existing one to show 
your issue.

> MapMessage.getChar does not handle if the backing map contains String or UTF8

>                 Key: AMQ-5629
>                 URL: https://issues.apache.org/jira/browse/AMQ-5629
>             Project: ActiveMQ
>          Issue Type: Bug
>            Reporter: Endre Stølsvik
>
> Compare to AMQ-5628.
> Read up on http://docs.oracle.com/javaee/1.4/api/javax/jms/MapMessage.html to 
> see that getChar(key) shall be able to compute for something that was stored 
> as a String.
> ActiveMQMapMessage, line ~312:
> {code}
>     public char getChar(String name) throws JMSException {
>         initializeReading();
>         Object value = map.get(name);
>         if (value == null) {
>             throw new NullPointerException();
>         }
>         if (value instanceof Character) {
>             return ((Character)value).charValue();
>         } else {
>             throw new MessageFormatException(" cannot read a short from " + 
> value.getClass().getName());
>         }
>     }
> {code}
> Notice the absent handling of String or UTF8Buffer.
> Notice ALSO the wrong wording in the Exception "cannot read SHORT from.." 
> when we're in the CHAR getter.
