    Hi @spmallette 
    We are a team of researchers from Iowa State, The University of Texs at 
Dallas and Oregon State University, USA. We are investigating common/repeated 
code changes.
    We have four short questions regarding the change in the image below which 
is part of this commit.
    
![image](https://cloud.githubusercontent.com/assets/2257582/23099532/1e6c6ff2-f62f-11e6-95e3-10572f31edf7.png)
    
    Questions:
    
    Q1- Is the change at these lines similar to any other changes (from other 
locations of the same commit or from other commits)? (yes, no, not sure)
    
    Q2- Can you briefly describe the change and why you made it? (for example, 
checking parameter before calling the method to avoid a Null Pointer Exception)
    
    Q3- Can you give it a name? (for example, Null Check)
    
    Q4- Would you like to have this change automated by a tool? (Yes, No, 
Already automated)
    
    The data collected from the answers will never be associated with you or 
your project. Our questions are about recurring code changes from the developer 
community, not about personal information. All the data is merged across 
recurring changes from GitHub repositories. We will publish aggregated data 
from the trends of the whole community. 
    We have a long tradition of developing refactoring tools and contributing 
them freely to the Eclipse, Netbeans, Android Studio under their respective 
FLOSS licenses. For example, look at some of our recently released refactoring 
tools: http://refactoring.info/tools/
