Log:
Implemented: New UtilMisc method collectionToString(...) building safely a
String with the given collection and delimiter
(OFBIZ-9397)

The added method UtilMisc.collectionToString(Collection values, String delimiter)
creates a String from the values of a collection, separated with the given
delimiter. This is done in a safe way without a "null" literal.

Thanks: Martin Becker
