NullPointerException in TokenRequestTask execution

See original GitHub issue

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

Caused by java.lang.NullPointerException
       at java.io.Reader.<init>(Reader.java:78)
       at java.io.InputStreamReader.<init>(InputStreamReader.java:72)

       at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641)
       at java.lang.Thread.run(Thread.java:764)

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?

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.

Should now be fixed by the merge of #414.
