ERROR: "Link of class 'Lorg/cyanogenmod/focal/FocusManager;' failed", branch cm-10.1 failed to run on android 4.0.4

I see the FocusManager.java file is just there, while the logcat says: Link of class 'Lorg/cyanogenmod/focal/FocusManager;' failed
The full logcat is here:

Link of class 'Lorg/cyanogenmod/focal/FocusManager;' failed

Lorg/cyanogenmod/focal/FocusManager;.refocus ()V

why .refocus() is "virtual method"? isn't the method is defined in the java file?

and this also confuses me ;(
