asm config file help?

I am trying to make the tasks and the targetTasks fields in EntityLiving non final but it didnt seem to work.

i have this in my *_at.cfg file:

#EntityAITask remove final
og.c -f
og.d -f

in eclipse its console it says this:

Loaded 3 rules from AccessTransformer config file *_at.cfg

but when i run the game trough eclipse it didnt remove the final modifier.

and gives the following error:

2013-10-08 22:10:30 [iNFO] [sTDERR] 	The final field EntityLiving.tasks cannot be assigned
2013-10-08 22:10:30 [iNFO] [sTDERR] 	The final field EntityLiving.targetTasks cannot be assigned
