So i'm afraid that this kind of exceptions is related to performance.

Hi Majid,

how much heap do you allow for the JVM that launched Eclipse?

Hi Majid,

that should be sufficient. How many models do you have in your
workspace? Do you have many open editors? How large is the average model
(in LoC)? Do you have plugins installed that consume a lot of memory?
Would it be possible to provide an example that reproduces the problem?

Regards,
Sebastian

I think it was the source of problem.
I know it's related to bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=301795, so i get the last integration build for 1.0.0.
But this version doesn't generate project correctly(especially the class MyDslParser).

Thanks,
majid

Hi Majid,

please use this update site:

http://download.itemis.com/updates/nightly

You'll have to select Xtext, MWE2, MWE, Xpand and Xtext-Antlr.

Sebastian

Hi Sebastian,
First thank you for your help.

I used the nightly build to generate the project correctly , but for the problem related to java heap space i removed the option backtrack from the workflow , and it works Smile

Best Wishes,
majid.

Hi, I am not yet running on the latest version of Xtext.
I just got hit by OutOfMemory (heap space) as well.
I found that mwe launch configuration had vm parameter settings that I
needed to override. I have not figured out the smallest possible, but
this works for me (and I am using backtracking).

-Xms40m
-Xmx1024m

(-Xmx was 256m, but needs to be at least 512m on 64 bit mac)

(but just changing them for the IDE itself does not help when they are
also specified in the mwe launch configuration for your grammar).
