>             Project: Axiom
>          Issue Type: Bug
>          Components: DOOM, LLOM
>    Affects Versions: 1.2.12, 1.2.13

>            Assignee: Andreas Veithen

> As part of an Axis2 workflow, my code validates incoming messages against 
> schemas.   This seems to work in all cases except when the incoming message 
> contains an MTOM attachment.
> The code constructs a Source object for the part of the message to be 
> validated, then calls the "validate" method on a properly constructed 
> javax.xml.validation.Validator object:
> Source validateMe = new OMSource(messagePart);
> validator.validate(validateMe);
> The error generated looks like this:
> java.lang.NullPointerException
>  at 
> org.apache.axiom.om.impl.llom.OMTextImpl.getTextCharacters(OMTextImpl.java:272)

> ----
> By the time it reaches my handler, I'm not fully certain what should be in 
> the MTOM attachment element should contain, as it's reasonable to assume that 
> the attachment has been extracted by then.   A NullPointerException doesn't 
> seem appropriate, however.
> A logging statement does show the attachment inline, encoded in Base64 
> (though I believe all incoming MTOM is represented that way if the envelope 
> is printed for a log).
