> {{ex}} may be swallowed when {{close}} highlighted in the code throws exception.  Thanks
[~qwertymaniac] for pointing this out.
> BTW, I think we should be able to consolidate the two {{is.close()}} in the above code,
so we don't close the same stream twice. The one in the {{finally block}} may be called after
an exception is thrown or not, and it may throw exception too, we need to be careful not to
swallow exception here too.
