adding taint tag and method make image launch failed

[jinxh...@gmail.com]

hello all:

I tried to add taint tag and method in Taint.java , launch system.img failed after building . But after removing the code I inserted , it launch success. 

I wonder if I can add taint tag and method in Taint.java? or there is lack of other step ?

Appreciate your kind help
