Cobertura generates my reports for code coverage, but the coverage shows as 0%

All of my reports get generated, but my coverage shows as 0%. I even created one dummy test to make sure it wasn't the way my tests were written, and it doesn't show for the one dummy class I'm covering. Here is my Ant build for this:

<?xml version="1.0" encoding="UTF-8" ?>

you must set debug on when you compile java

<javac **debug="on"** srcdir="${testcase-unit-only.path}" destdir="${testcase-unit-only.output.path}">

I had the same ant build scripts. It worked on my local workstation, but didn't on jenkins server. But server had jdk 7 and workstation jdk6. After changing jdk on jenkins server to jdk6, code coverage generates without any problem.

One thing I notice is that in the depends list for the run.cobertura target you instrument the compiled classes before you compile them. That might work if you run twice, assuming the compiled classes from the first run are not cleared down, but doesn't seem quite right. On the first run if there are no instrumented classes, your report would be empty.
