Would it be possible to explain why this didn't happen before? The file channel position is 0 and I think transferFrom is called to transfer up to 1MB from a pipe source. The method is called with the interrupt status set so attempting from the pipe source will throw ClosedByInterruptException. I'm wondering what this didn't happen before your change.
