Can this issue be reopened? I occasionally see this error in our product's builds. Unfortunately, I don't know how to reproduce, either, but I suspect it might happen only when one or more tests have failed (just a hunch). Stacktrace follows:

Testing. Looks okay

Hi William,

Not sure exactly what is causing this sporadic bug, however I have added a defensive check for the NPE and will upload a patched build for you here if you wish.
Otherwise, we will be releasing 2.4.2 - hopefully soon with this patch.

Please let me know what's best for you,
Cheers,
Nick

Hi Nick,

I think we'll try picking up 2.4.2 when it's out so we can try out the new filteredElements feature in the coverage reports.

Hi William,

2.4.0 is already out if you wish to start using the filteredElements column already.

Cheers,
Nick
