commit 2658deaf326c58454e260a9b6777ced15ec095dc

    Remove self-assignment statement. (#2445)
    
    Removed a self-assignment of the hostPortString variable to itself.
    
    If the hostPortString is non-null, nothing happens and the variable is 
unchanged. If the hostPortString is null, a NullPointerException is thrown. 
There is no need to assign it to itself.
    
    Change suggested by errorprone analysis.
    
    Added a message to the requireNonNull method indicating the cause of the 
NullPointerException.
    
    Also, added java.util.Objects import remove need for fully qualified path 
to requireNonNull.
