Does EMF Query 1.x work with J2SE 1.4?
Mostly, yes. The core EMF Query framework works with EMF 2.2 or higher and J2SE 1.4.
However, the OCL extensions in the org.eclipse.emf.query.ocl plug-in require:
- For Query 1.2: OCL 1.2 and EMF 2.4
- For Query 1.1: OCL 1.1 and EMF 2.3
Consequently, using OCL with EMF Query requires J2SE 5.0 or greater. See also EMF 2.3 JVM Requirements.
