You don't include the initial condition in your code, but I'm assuming
that the first line is hit: response.setContentLength((int)length);
int in Java is defined to be 32 bit, and always signed. That means that
any value larger than 2^31 or Integer.MAX_VALUE can't be expressed in
int as a positive number. In fact, anything between 2^31 and 2^32 will
be interpreted as a negative number, so you're effectively setting the
content length to be negative.
Note that there's also a setContentLengthLong method
