The JavaDocs say ` The behavior for the case where the inputand/or output stream is asynchronously closed, or the thread interrupted during the transfer, is highly input and output streamspecific, and therefore not specified.`. So there is seems to be no *essential* need to do something *particular* in that case (the caller cannot further use the BIS, just like after an IOE: `It is strongly recommended that both streams be promptly closed if an I/O error occurs.` -- which is what *I personally, as a user of BIS* would do after async close), but if you *want* that we reach a particular outcome, then just tell me what outcome you envision.

@dfuch Just to learn about OpenJDK rules: Why? I always thought that CSR is only needed when breaking *documented* behavior. Do you have a link to the official rule that proofs your claim in *this* case (i. e. *non-documented* behavior)? Thanks! :-)
