How to create a Java non-blocking InputStream

You can't. Your question embodies a contradiciton in terms. Streams in Java are blocking. There is therefore no such thing as a 'non-blocking InputStream'.

Reader.ready() returns true when data can be read without blocking. Period. InputStreams and Readers are blocking. Period. Everything here is working as designed. If you want more concurrency with these APIs you will have to use multiple threads. Or Socket.setSoTimeout() and its near relation in HttpURLConnection.
