Appauth-android: NullPointerException in TokenRequestTask execution

[trebouillon]

I use the version 0.7.0 of the library and sometimes get the following error:

Caused by java.lang.NullPointerException

       at java.io.InputStreamReader.<init>(InputStreamReader.java:72)

This crash happens when the input stream is null, e.g. the server is out of business.

Would it be possible to handle a null input stream as network error?

Yep, looks like a bug, will fix.

I've faced with the same issue or similar and can't find any solution at the moment.
I'm using version 0.7.1.
Here is the error output.
