Under the conditions:
- 2 KiePackages with the same package name but different rules
- Those packages are used by a kbase so "inUse = true"
- Create another kbase and call kbase.addPackages() for those packages
MVELDialectRuntimeData has a problem in merging mvelReaders so later rule execution fails with NullPointerException.
