> 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.
