Vladimir Ozerov commented on IGNITE-5204: ----------------------------------------- Is it fine that UTF8 convering method may return null? > The Unicode character in the value of a field which are included in an > un-unique index will cause "stack overhead" exception > ---------------------------------------------------------------------------------------------------------------------------- > > 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 > > Attachments: IgniteSqlIssue5204Test.java > > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
