OpenJPA not supporting count(*) syntax
--------------------------------------

                 Key: OPENJPA-566
                 URL: https://issues.apache.org/jira/browse/OPENJPA-566
             Project: OpenJPA
          Issue Type: Bug
          Components: query
    Affects Versions: 1.0.2
         Environment: Spring 2.5.3, JDK 1.5.
            Reporter: Mathias Bogaert
            Priority: Blocker


When executing a simple query using the (assumingly) valid count(*) syntax, accepted by Hibernate,
OpenJPA throws an exception.

Caused by: <openjpa-1.0.2-r420667:627158 nonfatal user error> org.apache.openjpa.persistence.ArgumentException:
An error occurred while parsing the query filter 'SELECT count(*) FROM Order instance'. Error
message: <openjpa-1.0.2-r420667:627158 nonfatal user error> org.apache.openjpa.kernel.jpql.ParseException:
Encountered "*" at character 14, but expected: ["(", "+", "-", ":", "?", "ABS", "AVG", "COUNT",
"DISTINCT", "LENGTH", "LOCATE", "MAX", "MIN", "MOD", "SELECT", "SIZE", "SQRT", "SUM", <DECIMAL_LITERAL>,
<IDENTIFIER>, <INTEGER_LITERAL>].
