android 5.0以下系统。修改bean中get或set方法（这个方法别的类有调用），会报not instance of。

Start by reproducing the Android 5.0-and-below failure described in the verifier logs, then inspect TestBean, TestBean_CF, and TestFragment.setData2Page, including the referenced MainActivity.java:87 call path. Done means changing the bean getter or setter no longer produces the reported VerifyError or rejected opcode.
