> 1) BasicClassIdMapper.typeId do not perform to-lower-case conversion.
> 2) BasicClassIdMapper appears to behave in absolutely the same way as IdMapperWrapper(null). Then why do we have two constants DFLT_ID_MAPPER and BASIC_CLS_ID_MAPPER?
> 3) We can slightly improve perofrmance introducing internal ID mapper with two implementations - default (lower case hash code) and delegating (will user-supplied mapper). This way we will reduce amount of virtual calls in the most common case.
