M2EE error

0
Dear all, I am getting a run time Nullpointerexception… though I know very well what that is, it seems there is no clue to be got from the stack trace about how to fix this in Mendix (see below). Any suggestions? Redeploying to another team server is not an option due to stakeholder presence. Hope you can help. Thanks beforehand.

Okay – resolved: I deleted my deployment folder and unpacked the old data snapshot. That made it work again. I am still wondering how I could have gathered that from this log though. Any ideas?
