You have some code that involves a line reader that isn't included in your post that is throwing a null pointer exception:

 ...Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'int java.io.Reader.read(char[])' on a null object reference
    at java.util.Properties$LineReader.readLine(Properties.java:435)..
