JPA EclipseLink - The expression is not a valid conditional expression

Question

Although there is nothing wrong with this query, eclipselink throws this exception.

[34, 130] The expression is not a valid conditional expression.

I am trying to run Spring boot with Jpa/eclipselink in windows 7.

The problem occurs when I change system language to Turkish.

Why eclipselink doesnt work on OS that uses Turkish lang? When I change system language to English, it works fine.

Please somebody help me out.

Query:

return em.createQuery("select c from Orderdetail c where c.status=1 and c.triggertime > 0 and c.printstatus = 0 and c.idorder.idorderstatus.id in (1, 4)").setHint(QueryHints.REFRESH, HintValues.TRUE).getResultList();

This is another query parsing error. Full log

    Exception Description: Syntax error parsing [select c from Orderdetail c where c.status=1 and c.triggertime > 0 and c.printstatus = 0 and c.idorder.idorderstatus.id in (1, 4)]. 
[34, 131] The expression is not a valid conditional expression.

Answer 1

[SOLVED]

After spending hours of debugging, I found the reason of this exception.

LSS: Exception was occurring in HermesParser which is query parser in eclipselink. Starting from there, i found a code that converts in, and, or, like etc parts of jpql to uppercase.

Part of my query(failing to parse).

and c.idorder.idorderstatus.id in (1, 4)

Here and and in gets converted to uppercase AND and IN. The problem is, in turkish, uppercase of i letter is İ(dotted I), so upprecase of in is İN which is incorrect expression. When Operation system language is in Turkish, uppercase method converts i to İ. That was the problem.

I changed all lowercase letters in jpql to uppercase beforehand, and solved the problem.

Hope it helps someone else ever encountered with this problem
