A JPA 2.1 attribute converter for ReadOnlyStringMaps in LogEvents. This converter is only capable of converting to Strings. The convertToEntityAttribute(String) method throws an UnsupportedOperationException. If you need to support converting to an entity attribute, you should use the ContextMapJsonAttributeConverter for conversion both ways.
