[mdt.dev] Can MDT/OCL make MDT/UML2-Tools useable on Helios?

[Ed Willink <ed@xxxxxxxxxxxxx>]

Hi Kenn

UML2-Tools fell off the Helios train, and Papyrus is not yet ready to 
replace it.

Users therefore need to run the Galileo release on Helios, but the 
Galileo release has a spurious dependency on org.eclipse.emf.ocl 1.x 
that was deprecated and so removed from Helios. Installation fails.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=318941 provides a workaround.

Since UML2-Tools is unlikely to rebuild, it would be nice to include the 
workaround in MDT/OCL 3.0.1, but any compatibility org.eclipse.emf.ocl 
should be 3.x so UML2-Tools installation would still be broken.

Is it permissible to have beyond end of life 'compatibility' releases 
that totally break API contracts thereby allowing the 
org.eclipse.emf.ocl 1.4.300 workaround in MDT/OCL 3.0.1?

    Regards
