Bug Description:
RFE: Replace conditional of primitive and object to use boxing instead of unboxing

Currently using the conditional operator on a primitive and object can be very error prone.
The code below will throw a NullPointerException.
If boxing was used instead of unboxing we would not have this problem.
(Bug Report 6303028 looks like they are asking for the same things)

Workaround: box the primitives ourselves (ie in the case below use Integer c = a ? new Integer(1) : b ? new Integer(2) : null; instead)

public class Test {
  public static void main(String[] args) {
    boolean a = false;
    boolean b = false;
    Integer c = a ? 1 : b ? 2 : null;
  }
}
