I read the doc. you pointed out as such: when "out.close()" was called, the "writeChannel" was not closed; when "readChannel.close()" was called, the "reader" itself was not closed. So, looks like you only need to do one or the other. It may have to do with how closing is implemented on the channels.
So remove "out.close()", and see if the exception would go away.
