Behavior of readInto() on stdin seems to have changed. In an older (mid-December) version, our application could call stdin.readInto(...) and terminate. Somewhere before version 2918, the application now fails to terminate unless we add a close() method on stdin.

FYI: We have not set any handler callbacks.

Is this behavior expected/intended?

This is currently the case on at least OS/X, can try on other platforms.

stdin is an InputStream and you need to setup handlers to get the data. The API for all streams is asynchronous. Calling readInto when you have not received a onData callback is not guaranteed to give you anything.

This sounds like the intended behavior because you probably never read out the data. Could you provide example code so we can be sure?

I undertand this is a bad use of the API -- I just thought it should not hang.

Some time after Jan 3, this issue has been resolved and I can no longer reproduce it.

We can now close this.

Thanks,
David
