Subject [jira] [Commented] (AMQNET-404) ActiveMQByteMessage Content accessing multiple times wipes the property
Date Sat, 19 Jan 2013 21:58:12 GMT

    [ https://issues.apache.org/jira/browse/AMQNET-404?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13558099#comment-13558099

Daniel Marbach commented on AMQNET-404:
---------------------------------------

Ok. Didn't know that. But this design is completely against the framework design guidelines.
Accessing a property multiple times should return the same result.

> If you have an IBytesMessage and for example do the following:
> byte[] content = null;
> if (message.Content!= null)
> {
>    content  = message.Content;
> }
> Accessing content the first time will return the correct data.
> Accessing a second time the content property will return an empty byte array which has
the length of the data but all bytes are zero.
> It is OK that the content property is evaluated lazily but it should not return different
data when accessing multiple times. So accessing the property the first time should read the
buffer and assign it to a field and then always return that byte buffer.
