Richard Zowalla created OPENJPA-3044:
----------------------------------------
Summary: JPQL does not accept a sign in front of a path, e.g.
SELECT -n.intA
Key: OPENJPA-3044
URL: https://issues.apache.org/jira/browse/OPENJPA-3044
Project: OpenJPA
Issue Type: Sub-task
Reporter: Richard Zowalla
JPQL does not accept a sign in front of a path or other arithmetic primary:
{code}
SELECT -n.intA FROM NumericOperands n
{code}
fails to parse. The JPQL grammar ({{JPQL.jjt}}) only allows a sign on numeric
literals ({{negative()}}); {{arithmetic_factor}} has no optional sign. The
Jakarta Persistence BNF defines {{arithmetic_factor ::= [{+ | -}]
arithmetic_primary}}, so {{-n.intA}}, {{-(n.a + n.b)}} and {{+n.intA}} should
be valid. The criteria API ({{cb.neg(x)}}) works.
Found while working on OPENJPA-3035.
