> While debugging an issue involving usage of {{CloseShieldOutputStream}} I discovered
that {{ClosedOutputStream#flush}} is not overridden and will silently succeed. Not sure how
much of a breaking change this might be but I think it makes more sense for {{ClosedOutputStream#flush}}
to throw. This is only really meaningful in contexts where multiple streams are being chained
together and some of the streams before {{CloseShieldOutputStream}} perform buffering, but
it would make behavior more consistent for these more complex use-cases.
