OCL/New and Noteworthy/2020-03

Eclipse OCL New and Noteworthy items for the 2020-03 (6.11.0) release.

Release Overview

This minor release fixes a few bugs and provides enhanced extensibility for OCL-based applications such as QVT.

The addition of and2/implies2/not2/or2/xor2 provides first class support for what most OCL users want 99.9% of the time; Boolean operations that crash if their inputs are not 2-valued and consequently only ever return 2-valued results.

The Bug 560196 fix also available in 6.10.1 fixes a major howler in regard to saving fom the OCLinEcore editor.

Eclipse versions

The prevailing Eclipse OCL release candidate is auto-tested every week on Oxygen, Photon, 2018-09, 2018-12, 2019-03, 2019-06, 2019-09 and 2019-12 platforms using Jenkins on Linux.

2020-03 release should be installable on Mars and Neon platforms provided Xtext 2.9 or greater is also installed.

The 2020-03 sources are buildable on 2020-03 only.

Java versions

Java 8 on Windows was used to develop and test the milestones of this release.

Java 12 on Windows was briefly used to maintain and test the 2020-03 release candidates. It appears to work although Java code generation/compilation seems nearly three times slower - see Bug 565563.

Java 8 on Jenkins, Linux was used to build and test the release candidates.

The Classic Ecore/UML plugins have been tested on Mars, Neon, Oxygen and Photon and on a Java 5 Virtual Machine. Standalone execution requires only the org.eclipse.osgi plugin from Eclipse Kepler or a spoof of org.eclipse.osgi.util.NLS and org.eclipse.osgi.framework.

The Pivot plugins require at least a Java 8 Virtual Machine and at least Xtext 2.9.1. Testing on Oxygen has a couple of test failures. Testing on Mars and Neon has a few editor/console startup failures.
