A类调用B类，B类是一个单例类，在B类中添加一个方法，然后在A类中调用B类中的新加方法，可以生成patch文件，但代码中addPatch后，崩溃，提示A类中找不到B_CF类。

Start with the addPatch call and the MainActivity.java:472 stack-trace entry, then inspect how the singleton's generated TestPatch_CF class is produced and loaded. Reproduce the patch that adds a method to the singleton and verify that applying it no longer causes NoClassDefFoundError or ClassNotFoundException.
