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?
> AuthenticatedURL will NPE if server closes connection
