When I'm trying to add a file with CMIS-Explorer
(http://code.google.com/p/cmis-explorer/) I'm getting a NullPointerException.

Problem is cmis-explorer  send Atom document that does not contains CMIS 
elements.
We are not supported it at the moment. But will add this possibility soon.
This described in specification:
-----
POSTing other document formats: (AtomPub)
The behavior is repository specific when a non Atom entry or an atom document 
without the
CMIS elements is posted to a folder collection.
For example, the repository MAY auto-create a document with a specific type
(document) the
client could edit.
If the repository does not support this scenario or another exception occurs, 
then
the repository
MUST return the appropriate HTTP status code.
----
Any way NPE is unacceptable.
