Hi guys,

I just spent quite a while trying to debug a problem where in I was 
unable to get responses from SQL MA. Turns out, its all because of new 
line characters in xml tag contents which were introduced either in the 
store or in the request message.

When any part of the service implementation is trying to compare two 
strings - one hardcoded within the implementation (such as eventType 
value) and the second one coming from the xml message (via the Message 
bean), even if the strings are similar except for new-line characters, 
the checks fail. This definitely needs to be taken care of.

Initially I thought that we could take care of this at the Message bean 
level (by stripping empty strings around a text). But I am not 100% sure 
of the outcome. I am not sure because for some strings, white spaces 
*between the text* are important (command line mp for example). Jason, 
what do you think? I found out the String.trim() method will remove 
leading and trailing white spaces but not sure about white lines?

Any thoughts anybody? This bug can cause problems because the 
configurations at least are created by the users and its difficult to 
get them to remove such white spaces and new lines. It affects SQL MA 
for sure and maybe RRD MA (Ilias?)

Loukik.
