[Building Sakai] Assignment Download All Problem

[Omer Piperdi]

We are seeing issues with "Download All" link in Assignment Submissions. 
It creates a zip file with 0 byte, nothing in zip file and no error in 
catalina.out as well..

Anyone seen this before?

This is on 2.7 with Oracle 10g and Tomcat 5.5.29.

Thanks
Omer
