[hibernate-issues] [Hibernate-JIRA] Created: (HHH-5085) Literals with leading zero in HQL validated as octal but used as decimal

[James Livingston (JIRA)]

Literals with leading zero in HQL validated as octal but used as decimal
------------------------------------------------------------------------

                 Key: HHH-5085
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5085
             Project: Hibernate Core
          Issue Type: Bug
          Components: query-hql
    Affects Versions: 3.3.2
            Reporter: James Livingston
            Priority: Minor


The grammar used to parse HQL/JPAQL treats numeric literals[0] with a leading 0 as octal (and 0x as hexadecimal), however those values are always converted[1] as base 10. This means that a literal 0100 will match a value of decimal one hundred, but a literal of 0108 will fail to validate due to the '8' character.

Either the grammar should not handle octal/hexadecimal, or the conversation should process them correctly.
