Hmm it sounds like a bug indeed but it's very hard to tell what's going on.
Can you provide some details on the data (body) your resource returns?

I&#39;m new to RestAssured (using 1.6.2). When I tried to read the content<=

of the response&#39;s body as a String, I got a NullPointerException.<br>
However, during debugging the REST server logs successful messages and<br>
the content length of the response is as expected, the result is<br>
there, I just can not read it. Then I tried to read the body as<br>
InputStream and it worked. So, is there a problem with my code?<br>
<br>
Response response =3D RestAssured.get(path);<br>
String token =3D response.getBody().asString();<br>
<br>
I also tried to use print() or prettyPrint() but I got the same<br>
results.<br>
The exception gets thrown in RestAssuredResponseImpl in<br>
<br>
private String convertStreamToString(InputStream is) throws<br>
IOException {<br>
=A0 =A0 Writer writer =3D new StringWriter();<br>
=A0 =A0 char[] buffer =3D new char[1024];<br>

}<br>
<br>
When I reach finally, the reader is already null again:<br>
java.lang.NullPointerException: Cannot invoke method close() on null<br>
object<br>
Any idea why I can&#39;t use asString or prettyPrint?<br>
<br>
Cheers!<br>
