Server crashes if given HTTP version cannot be cast to float, or the resulting float is too large

Issue

If given HTTP version string cannot be cast to a float, the server will crash. The server will also crash if the string can be cast to a float, but the resulting number is too large.
How to replicate:

Run the server
Open terminal, type:
telnet localhost 8080 GET / HTTP/NotNumericString
telnet localhost 8080 GET / HTTP/10000000000000000000.10000000000000000000000000000000
