My colleague Louis Wasserman reports:
Random.doubles(lowerBound, upperBound) does not behave gracefully in the presence of overflow -- specifically including when lowerBound or upperBound have magnitude in the range of Double.MAX_VALUE.
There is a relatively simple patch: if (upperBound - lowerBound >= Double.MAX_VALUE), return a double in the range [lowerBound/2, upperBound/2) and multiply it by 2.
