GMF Cursor error and Sirius compatibility with Eclipse 2025-06

[GlennPlou]

This issue reminds me of eclipse-gmf-runtime/gmf-runtime#93, I guess this Sirius issue will be fixed with the GMF Pull-Request.

Discussed in #612

Hey there,

I'm in the process of upgrading our application to use Eclipse 2025-06 and have updated the target appropriately. Unfortunately I'm running into an error when trying to open diagrams from an existing project. Oddly it does not happen when I create a new diagram and open that.

Just wanted to check that Sirius is indeed compatible when building against Eclipse 2025-06? I was originally on Sirius 7.4.8 and tried upgrading to 7.4.10 to see if that helped but no luck. It works fine in Eclipse 2025-03.

Cheers
Jonathan

I see that eclipse-gmf-runtime/gmf-runtime#93 has been merged, is there anything that needs to be done on the Sirius side? Or should this fix be available in the most recent Sirius/Eclipse version?

[pcdavid]

The fix (and the bug) is purely in GMF Runtime, in particular in version 1.16.7.
If you are stuck on Eclipse 2025-06, you should be able to update GMF Runtime only from https://download.eclipse.org/modeling/gmp/gmf-runtime/updates/releases/R202508120942/

Note that in the context of 2025-06, this fixes the crash, but the custom GMF cursors are displayed a black square. That's unfortunate, but there is no way around it with the version of SWT in Eclipse 2025-06.

GMF Runtime 1.16.7 is part of Eclipse 2025-09, which also includes fixes in SWT, so if you use the versions from 2025-09 everything should work.
