Steve Loughran commented on HADOOP-9363:
----------------------------------------

Looking at this. So the root cause is the back end isn't sending back a valid response; the client is NPEing. 

I'm looking at the code in the JDK to see how the NPE could be triggered, but it's not immediately obvious. I don't see any diffs between Java 7u45 and Java 8, so have to assume that if there is a problem, it's still there.

What about catching any RuntimeException raised as this point, rethrow it as an IOE, and including the URL at fault in the message?
