-----------------------------------
> PortableContext: rework ID mappers handling.

> Key: IGNITE-1953
> URL: https://issues.apache.org/jira/browse/IGNITE-1953
> Project: Ignite
> Issue Type: Bug
> Components: general, interop
> Affects Versions: ignite-1.4
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Priority: Critical
> Fix For: 1.5
>
>
> 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.
