BigInteger inspection problem

Perhaps I am doing something wrong. I am seeking to use the following statement:

BigInteger increment = new BigInteger.ONE;

or use in a for loop. The inspector flags it and states "Cannot find symbol ZERO"

I am not sure why it is flagging a parameter that is part of the BigInteger class.

Is there a setting I need to sdjust to get this to work properly?

Thanks in advance
