Rendering problem (?) in runtime Eclipse application [message #1863446] Fri, 02 February 2024 18:54 Go to next message

I am following the 15 minutes tutorial of Xtext. After I generate Xtext artifacts from the grammar and hit Run As → Eclipse Application, there always seems to be some problem rendering this window, and I cannot see any component there:

index.php/fa/43958/0/

I have been running some other EMF projects as Eclipse application but they never had this trouble before.

For your information, I have Eclipse Modeling Tools 2023-12 (4.30.0), with Xtext and Xtend 2.33.0, on an intel chip Mac. I have already tried switching between dark and light mode, restarting Eclipse, restarting my computer, and installing a new Eclipse for Java and DSL Developers instead, but none of them worked out.

Any help or idea is appreciated!

Thank you Christian for your reply! Indeed my run configurations for Eclipse application had this problematic JDK 17.0.10 as well. It turned out to work after I changed it to 21.0.1.

index.php/fa/43963/0/

Interestingly when creating an Xtext project it defaults to JDK 17, but for other EMF projects I had before, the run configurations were automatically set to JDK 21 (which is the default in my system) so they didn't have this trouble before.

if you have xtend files in project the compilation against target 21 wont work. this is why default is java 17

I see. So I will still stick to JDK 17. It also seems to work if I use other sub-versions other than 17.0.10.

Thanks again!
