QPIDJMS-48: update docs with new option
> inconsistent handling of property names in Message methods
> ----------------------------------------------------------
>
> Key: QPIDJMS-48
> URL: https://issues.apache.org/jira/browse/QPIDJMS-48
> Project: Qpid JMS
> Issue Type: Bug
> Components: qpid-jms-client
> Affects Versions: 0.1.0, 0.2.0
> Reporter: Jakub Scholz
> Assignee: Robbie Gemmell
> Fix For: 0.3.0
>
>
> The client validates the values passed to get/Set*Property methods, enforcing
> that they are valid Java identifier names. It does not however validate the
> values returned from/given to the getPropertyNames or propertyExists methods,
> meaning it could return (or indicate presence) of properties that dont meet
> the JMS requirements, but then fail to allow setting/accessing them.
> The behaviour of getPropertyNames or propertyExists should be updated to
> match the validating behaviour of the get/Set*Property methods. An option
> will be added to enable disabling the validation.
> Original Text:
> The Qpid C++ broker - which supports both AMQP 0.10 and 1.0 - delivers quite
> often messages with a property containing "." in the property name. In
> particular, the property "qpid.subject" can be seen quite often, because it
> is attached automatically to the message by some AMQP 0.10 clients.
> The current handling of message properties with "." in their name seems to be
> a bit strange in the Qpid JMS client. When the client receives a message with
> this property, its property name is returned by the method getPropertyNames()
> including the dot. However, when I try to call some method to actually get
> the property value - e.g. getStringProperty("qpid.subject"), I get an
> exception:
> javax.jms.JMSException: Identifier contains invalid JMS identifier character
> '.': 'qpid.subject'

> This causes problems when you client wants to iterate over all message
> properties and I think the behavior should be more consistent. If the
> property is returned by getPropertyNames(), then the get*Property() should
> work too. Or other way around - if get*Property cannot be used for such
> property, it should not be returned in getPropertyNames().
