Thanks for the quick answer Nicolas, I tried to increase the Java memory in the script but no better results. I will split the project in smaller parts. Not a big deal in this case. Thanks, Fabrizio 2015-04-21 10:30 GMT+02:00 Nicolas Anquetil <nicolas.anquetil@inria.fr>:
it is a know fact, not an error :-)
Basically, verveinej has to maintain several models of the project in memory to be able to do its job if the project is too big, this might end up exploding the memory and giving unexpected results
That's why we implemented the incremental parsing option
Now, what you are reporting looks like a bug, but because of the conditions, I am not sure it is really one, especially if it works fine when you split the project in 2
You also have the option of twicking the calling script to increase java memory In the past, (sun) java used to require contiguous memory (just like pharo) but jikes removed this constraint I believe the new oracle java removed the constraint also, so you might be able to go pretty high in memory on a java execution ...
Let us know if it works

PS: This seems like a Moose-dev question rather than a pharo-dev one

I'm using windows, not sure how to get the version of verveinJ. The same does not happen if I split the project in two parts and I parse them separately.
Is it known error or am I doing something wrong?
Thanks in advance, Fabrizio
