It's from my site. See http://www.servlets.com.

Most of these problems tend to be server or plug-in problems, probably
because the input stream feature of servlets isn't heavily tested by
most vendors. Can you try uploading the same files with the JSDK
server? That's the reference implementation.
Questions: What's in the extra bytes in the file you're uploading?
When it cuts bytes, does it always cut bytes off the end?

Right, there's not much in the class that could cause 150 bytes to
disappear. And the 1 Meg limit is user-settable, intended to protect
from denial of service attacks.
