Unescaped text messages in message detail

                 Key: AMQ-1534
                 URL: https://issues.apache.org/activemq/browse/AMQ-1534
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.0.0
         Environment: Browser
            Reporter: Elliotte Rusty Harold
            Priority: Critical


The new HTTP based queue view is very useful. However it has one really 
annoying bug that cost me some hours of debugging. Send a TextMessage to the 
queue containing a typical HTML or XML document such as 

<result></result>

Then look at that message in the web browser and look at the message detail to 
see the text of the message. The text appears to be blank, especially if the 
message only contains tags and white space as was the case for me. Even if it 
isn't completely blank, the tags will be missing.

The problem is that the text of the message is displayed raw and added to the 
HTML. This could even be a vector for XSS attacks since no escaping is 
performed.

Before displaying the text it should be escaped. That is, & should be converted 
to &amp; and < to &lt;. That should fix the critical problems.
