[eclipselink-users] 9L JPQL long literal incorrectly parsed in 2.4, 0, 2

[Mike Kienenberger <mkienenb@xxxxxxxxx>]

Starting in Ecllipselink 2.4.0, A JPQL long literal incorrectly is parsed.
The same issue is true for 2.4.1, but worked from Eclipselink 1.2 all
the way through 2.3.3.

simple example:
======
  public static void main(String[] args) {
        EntityManagerFactory emf =...;
        EntityManager em = emf.createEntityManager();

        String jpqlString = "select action from JpaAction action where
action.systemId = 9L";
        Query q = em.createQuery(jpqlString);
        System.out.println(q);
    }
======

Results in

EJBQueryImpl(ReadAllQuery(referenceClass=JpaAction sql="SELECT
DISTINCT id, inactivation_time, is_active, name, permission_category,
system_id FROM sec_action WHERE (system_id IS NULL)"))


Changing it to "9" from "9L" results in

EJBQueryImpl(ReadAllQuery(referenceClass=JpaAction sql="SELECT id,
inactivation_time, is_active, name, permission_category, system_id
FROM sec_action WHERE (system_id = ?)"))


Has the JPQL specification changed, or is this a bug introduced in the
2.4 branch?

http://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Basic_JPA_Development/Querying/JPQL#Literals
indicates that this is still valid grammar.

It's unclear to me after reading the specification whether 9L is a
valid format since only a Java integer exact numeric literal is
mentioned:

=====================================
4.6.1
Literals
A string literal is enclosed in single quotes—for example: ‘literal’.
A string literal that includes a single
quote is represented by two single quotes—for example:
‘literal’’s’. String literals in queries, like Java
String
literals, use unicode character encoding. The use of Java escape
notation is not supported in
query string literals.
Exact numeric literals support the use of Java integer literal syntax
as well as SQL exact numeric literal
syntax.
Approximate literals support the use Java floating point literal
syntax as well as SQL approximate
numeric literal syntax.
Appropriate suffixes can be used to indicate the specific type of a
numeric literal in accordance with the
Java Language Specification. Support for the use of hexadecimal and
octal numeric literals is not
required by this specification.
