methods that throws checked exceptions in a lambda block

[Wang Weijun]

This line does not compile

  Files.list(Paths.get("/secret")).forEach(x -> Files.write(x, new 
byte[Files.size(x)]);

because Files.write() and Files.size() throw IOE. Then what's the best way to 
make it work?

(I find some old threads on this on lambda-dev. Maybe we have a recommended way 
now?)

Thanks
