I have a call to getObjectsById(Collection, boolean ) that is throwing a JDOException the first time I'm attempting to retrieve an object. If I try again, then the second request succeeds. Any idea why this might occur? We're using ObjectDB 2.2.4_02. The collection being passed in is a HashSet

Logical operators in JPQL and in JPA criteria queries enable composition of complex JPQL boolean expressions out of simple JPQL boolean expressions. Logical Operators ObjectDB supports 2 sets ... part of its JDO support. Criteria Query Logical Operators Boolean Expressions and Predicates Boolean

including NULL , boolean literals ( TRUE and FALSE ), numeric literals (e.g. 100 ), string literals ... rules, as explained in the Comparison Operators page. Boolean Literals Similarly to Java and SQL, JPQL supports two boolean literals - TRUE and FALSE . Since JPQL is case insensitive, TRUE is equivalent
