1) fortunately no-one was suggensting that

 2) frankly its not big a deal - 3 machine instructions? The key thing fr me is the potential cnfusionin the cide over what value the field takes

   Mixing field initializers and constructors may lead to the fields
 getting initialized several time during the construction of an object.
 
 Consider the following class where the field x is considered to have the
 default value 5. Each time the object is constructed using the second
 constructor, x will be initialized two times.
 
 public class Class
 {
 private int x = 5;
 
 public Class() {
 }
 
 public Class(int x) {
 this.x = x;
 }
 
 ...
 }
