how to use bcel to tell if class was compiled with -g option?

What is an easy way to programatically tell if the class file was compiled with javac's -g option?

In particular, if I have this code

public void method() {
        FakeClass c = null; 
        //or something like below....
        FakeClass c = Factory.create();
}

With debug on, visitLocalVariable is called, when the class is compiled without it on, visitLocalVariable is not called, but is there an easier way to tell this like when I get all the instructions from the method, could I go through and look for an one of these...

aconst_null[1](1)
astore_1[76](1)

And if I find one, what would I do?

thanks for any help on this.  This is my last hurdle,

thanks,
