I've tracked the issue to the use of java.net.HttpURLConnection without setting
the contentLength (in some cases) and not using 'fixed length streaming mode'
when contentLength is available.
I'm attaching a patch that works for me with the DeployTask. I know that
org.apache.catalina.ant.AbstractCatalinaTask is subclassed by many tasks, but I
haven't tested all of those.
I can probably provide some code to reproduce if needed.
