We should have a better error message for the following issue mentioned on the mailing list.

I forgot add tmpRef to locals ...

body.getLocals().add(tmpRef);

It solve problem! :)

Hmmm, I can't see anything immediately wrong, but...

Actually Result:
java.lang.NullPointerException at line in my transformation:
units.insertAfter(Jimple.v().newInvokeStmt(Jimple.v().newVirtualInvokeExpr(tmpRef, toCall.makeRef(), intLocal)), as3);

... at this line of yours, which pointer exactly is null? Did you check with a debugger?

Cheers,
Eric
