             Summary: MboxParser wrongly concatenates multiple text lines into 
single header line
                 Key: TIKA-2044
                 URL: https://issues.apache.org/jira/browse/TIKA-2044
             Project: Tika
          Issue Type: Bug
    Affects Versions: 1.13
         Environment: Tika 1.13, and 1.14 nightly build at the time of this 
writing
            Reporter: Vjeran Marcinko


MboxParser combines multiple text lines into single header value by (suposedly) 
using LIFO structure (stack - java deque), but instead it uses FIFO (queue) to 
fetch last inserted line and to extend it with current line in incorrect way:

Current code:
Queue<String> multiline = new LinkedList<String>();
... few lines below...
String latestLine = multiline.poll();

Whereas it should be:
Deque<String> multiline = new LinkedList<String>();
... few lines below...
String latestLine = multiline.pollLast();
