public class ZeroTransformer extends StatedTransformer
dex mix use as integer 0 and object null. the following code is validate in dex, but invalidate in .class 
     a=0
     if x>0 goto L1
     L2: [b=phi(a,c)]
     useAsObject(b);
     c=getAnotherObject();
     goto L2:
     L1: [d=phi(a,e)]
     useAsInt(d);
     e=123
     goto L1:

we transform the code to 

     a1=0
     a=0
     if x>0 goto L1
     a2=0
     L2: [b=phi(a1,c)]
     useAsObject(b);
     c=getAnotherObject();
     goto L2:
     L1: [d=phi(a,e)]
     useAsInt(d);
     e=123
     goto L1:
