In the "io.debezium.relational.TableSchemaBuilder.createValueGenerator" method,there are some codes bellow:

return (row) -> {
Struct result = new Struct(schema);
for (int i = 0; i != numFields; ++i) {
Object value = row[recordIndexes[i]];
ValueConverter converter = converters[i];
if (converter != null) {
value = value == null ? value : converter.convert(value);
try

catch (DataException e) {
Column col = columns.get;
LOGGER.error("Failed to properly convert key value for '{}.{}' of type {} for row {}:",
columnSetName, col.name(), col.typeName(), row, e);
}
}
}
return result;
};

In extreme cases, row.size is not equal numFields,so ArrayIndexOutOfBoundsException throws.

eg. If Failed to commit offsets,and the connector task quit.Before we restart the connector,an column added ,and new table schema generated.So the data from old offset not matches current table schema .Bellow codes throw an ArrayIndexOutOfBoundsException
