Thank you for pushing on this. Based on delivery, I merged #7999 and #7982 in that order. That unsurpringsly worked correctly (the first reverting the first fix try, that prevented the next revert to apply, the latter reverting the offending change itself).

The resulting build successfully loaded all modules from enterprise, java and webcommon cluster, without raising an exception.

So assuming the final merge order will be the one described above, from my POV this is good to go.

Thanks again.
