Axis Null Pointer

Hi all,

can anyone provide any clues about why the following stack trace might be happening?
I believe it's related to attachments and chunked vs non-chunked requests.

If I turn chunking off I get the below stack. If I turn it on then WO's not liking the lack of Content-Length.

WO5.4.3
