IGNITE-5204: Fixed NPE on certain data with index inlining

> Key: IGNITE-5204
> URL: https://issues.apache.org/jira/browse/IGNITE-5204
> Project: Ignite
> Issue Type: Bug
> Components: cache, sql
> Affects Versions: 2.0
> Environment: windows server 2012, JDK 1.8, X64
> Reporter: Chris Wang
> Assignee: Sergey Kalashnikov
> Priority: Critical
> Fix For: 2.1

> When put "草DX009090" as the value of BillId, which is a field of entity
> Bill. If I define a index includes the BillId, and execute the query like
> "select * from Bill where BillId=’草DX009090‘ in the H2 debug console, there
> throws an exception by the H2 with a code 5000.
> another scenario is, I have two entities, "Bill" and "Detail", both have
> field "BillId". If either of them have value like "草DX009090" and execute the
> query like "select bill.* from bill left join detail on
> bill.billid=detail.billid", the whole ignite cache node will halt ( suppose
> there should be an stack overhead exception, dead loop).
> ======================
> I think the issue should relate to hash computing on the unicode character.
