I debugged through it: The vector causes `norm1` and `norm2`, as well as `sum` to get `Infinity`. `Infinity/Infinity` results in `NaN`. So it is not caused by sqrt. In general you are right this might happen with any vector if the exponent overflows while summing up the component squares. I am not sure how to work around that. Maybe it should return 1, if the sqrt gets infinity? -- This is an automated message from the Apache Git Service.
