null pointer on subject name

Hello,
if the attribute associated to the name field in the subject source description has no value for a person, then USDU terminates with a NullPointerException error (cf. annex below).
Agreed that an empty name is bad, but a log message saying "Warning: no value found for Grouper field name of user jsmith" instead of an exception dumping the java stack would be nice (and would have saved me hours).
