Bug fix changes
The following MDT-OCL 3.0.0 bug fixes obviously change behaviour slightly.
| Bug fix | Related bug/s | Owner | Adopting Milestone |
|---|---|---|---|
| Give if atomic precedence | 184048 | EDW | M3 |
| Fix Integer Dot parsing | 288601 | EDW | M3 |
Environment changes
| Bug fix | Cause | Related bug/s | Adopting Milestone |
|---|---|---|---|
| Remove EModelElement inheritance of EObject:
this prevents use of eContainer() and eContents() |
EMF 2.6.0M4 | 255469 | M4 |
| Change UMLReflection.getContainerElement() return to List<? extends EObject>
this avoids a (valid) compilation warning |
JDT 3.6.0M4 | 298128 | M6 |
