Description

The CSVRecordLookupService assumes that the provided key is a String and attempts to cast the value to a String. If an integer, for example, is provided, it throws a ClassCastException.

SimpleCsvFileLookupService, on the other hand, more appropriately calls toString() to convert the value into a String. We should do this always.
