MappingException malformed error message in log

[MDeLuise]

Describe the bug
While throwing MappingException a malformed error message is printed.

For example throw new MappingException(StorableErrorCodes.INVALID_VALUE, "arg1", "arg2") logs Exception in thread "main" org.eclipse.kapua.service.storable.exception.MappingException: The value of mapping arg1 of value arg2 is not compatible with type {2}.

MappingException is not throwed anywhere in the code, but its subclasses (InvalidValueMappingException and UnsupportedTypeMappingException) are. For example in MappingUtils.java there is throw new InvalidValueMappingException(e, name, value, Date.class).
