public ObjectReference thisObject() {
    validateStackFrame();
    MethodImpl currentMethod = (MethodImpl)location.method();
    if (currentMethod.isStatic() || currentMethod.isNative()) {
        return null;
    }
    if (thisObject == null) {

        if (Assert.ASSERTS_ENABLED) {
            Assert.that(values.size() > 0, "this is missing");
        }
        // 'this' at index 0.
        if (values.get(0).getType() == BasicType.getTConflict()) {
          return null;
        }
