> 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.
