[Using Sakai] recurring error in sakai 2.9.x

Looks like it's the NPE on this line (as mentioned in the stack trace).

 return getNeedToPostFirst(currentUser, selectedTopic.getTopic(),
selectedTopic.getMessages()).contains(currentUserId);
I'm not sure how selectedTopic is null (getMessages always returns an
ArrayList) but some other places in this code check for it to be null so
probably a way to do it and need to check for NPE.
