StatusListener in twitter4j API


I am trying to create a twitterStream in order to store images of some twitter user in hard disk. I am filtering some username with some specific hashtags the statuses of the listed user and I am trying to store the url images. I have found code to do so, however I am facing two probs. First one, I found that I cant insert toggle breakpoint that is put inside statuslistener. I am getting the following message classNotFoundException(Throwable ) Source Not Found. Secondly when I am trying to run the code I am getting:

[Tue May 13 12:20:51 EEST 2014]Establishing connection.
[Tue May 13 12:21:23 EEST 2014]Connection established.
[Tue May 13 12:21:23 EEST 2014]Receiving status stream.
