That is kind of odd.  However, I compiled your Java code and then looked
at it using javap.  It also contains a specialinvoke:

   64:  aload_0
   65:  getfield        #11; //Field partner:LFriendly;
   68:  invokespecial   #16; //Method hugBack:()V
   71:  return

Usually, specialinvoke is used for constructors, but there are certain
other cases where it can occur.  I'm not especially familiar with them.
In any case, Soot is just processing what it gets.
