I tried to implement Clover plugin code coverage.

My requirement was to mark the build as unstable whenever a threshold is not crossed.

Out of the 3 Jenkins jobs it is implemented in, only one's build is marked unstable.

The others are marked successful, despite all 3 having the same threshold values.

I have checked that the coverage report is published in all the three projects.

Under what conditions does a clover plugin not a mark a build "Unstable", even if the actual coverage is less than the threshold?

Please let me know if any more information is required.
