Line 156 in class org.nhind.xdr.DocumentRepositoryAbstract 
This assigns to an array list but the value coming from threadData is single 
semicolon separated string of the concatenated addresses.
The result is that this single delimited string is pushed into the first array 
element. Later when it attempts to send using the values from this array list 
it fails.
