+1 Moreover, I wonder where this value comes from? I've never seen it before. Here are warnings that javac supports:

all,auxiliaryclass,cast,classfile,deprecation,dep-ann,divzero,empty,fallthrough,finally,options,overloads,overrides,path,processing,rawtypes,serial,static,try,unchecked,varargs

It doesn't look like one of Eclipse's warnings either.

Agree.
