chunked input bugfix

[Michael Smith <ms...@xn.com.au>]

Yesterday I saw a bunch of 500 errors come up from a servlet we're
running. 
Fortunately, it turned out that there was a full stacktrace in the log
file.
I think the error itself was due to transient network faults (or client
bugs)at the client end of things, so it's not a problem that tomcat
rejects it - but it shouldn't be throwing a NullPointerException and
returning a 500 error.

This should fix it.
