As of today, mod-inventory-storage (master) uses 29.4.0.
If I point to 29.5.0-SNAPSHOT, then tests start to fail..
Since changing RMB version fixes this, I assume it's a regresssion in RMB. Now that RMB has forked from 29.3.0 and 29.4 series are a branch of that, it is not trivial to tell what broke it.
The test makes use of runSQLFile. Perhaps that give a clue. See attached rmb-606.txt.
