Nor is such a mention required, therefore its omission is not an error. 
However, it's pretty clear that if 'isNan()' is true, then 'doubleValue()' 
must return 'Double.NaN'.  That's an API issue and not strictly something to 
find in the JLS.

So far not one of the things you've cited as an error has actually been an 
error in the JLS.  There've been some things difficult to understand, and 
you've made some errors, but none have actually come from the JLS.
