COPY fails with Object size of 0

[GoogleCodeExporter]

What steps will reproduce the problem?
1. PUT an Object into a Bucket
2. Perform a COPY operation on that object to the same bucket or a different 
bucket using the same or a different key. (COPY under any conditions)
3. See the errors.

What is the expected output? What do you see instead?
Expected output is that the copy succeeds and the Object is copied (by any 
means) and has a resulting size equal to the size of the original Object. The 
actual result is that a new Object is created at the specified destination with 
the specified name (key) with a file size of 0 bytes. When performing the 
operation using a 3rd party library it is common to see errors possibly due to 
the new ETag being different than the original file. When constructing the COPY 
http request manually (or via curl) no errors are thrown, but the result is the 
same.

What version of the product are you using? On what operating system?
Version: littleS3-2.3.0
Tomcat: 6.0.28-10ubuntu2
OS: Ubuntu 11.04 Natty Narwhal
