Simon Laws commented on TUSCANY-3099:
-------------------------------------

Scott's right. The OASIS spec tightens this up as this is driving an underlying 
JMS API that expects a number. I think we should stick with this restriction 
but we could put some validation in that gives a more sensible message if you 
don't put a number in. Sound ok?

>          Issue Type: Bug

>    Affects Versions: Java-SCA-1.5

>
> When a JMS binding has a headers/@JMSPriority attribute with a string value, 
> a NumberFormatException occurs when parsing the composite.  Looking at the 
> JMS binding spec, @JMSPriority has type string so I don't think it should 
> throw an exception in this case.
> The stacktrace:
> java.lang.NumberFormatException: For input string: "medium"
>         at java.lang.NumberFormatException.forInputString(Unknown Source)
>         at java.lang.Integer.parseInt(Unknown Source)
>         at java.lang.Integer.parseInt(Unknown Source)
