Hi Erik,
You're correct that STREAMED means that the HttpServletRequest was already
read previously.
I've tried it in one of our projects and got the same result.
The code looks fine according to API docs, so I assume it's a
bug/regression that needs further investigation.
In our case, Shiro reads the body, so I've tried to set up a new project
from the archetype.
However, I didn't get Eclipse+Maven to stop at breakpoints in the Jetty
Request class to see who's calling getReader()/getInputStream() before the
request body is converted/coerced to a String.
Cheers
Ben
