Jacob,
thanks for that hint ! Honestly speaking I was sure that there is no problem with JarCreator, cause JarCreator does not need to call any NormationClass.
But you are right, recompiling JarCreator does solve the problem. It seems that 'accidentially' I called in JarCreator a method that via some other classes tries to load the NormarionClass that are declared the DictionaryForMIDs.properties file. This problem is included in JarCreator already for a few releases, but somehow it never showed up before.
Ok, I will get that fixed and the upload JarCreator 3.5.0 !
