> In KMSClientProvider# createConnection
> {code}
> try {
> is = conn.getInputStream();
> ret = mapper.readValue(is, klass);
> } catch (IOException ex) {
> if (is != null) {
> is.close(); <== close may throw exception

> {{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.
