Wollok works badly (unusable) under ubuntu 16.04 (64 bits)

[lgassman]

Wollok works badly under ubuntu 16.04.

The Wollok IDE starts succesfuly, but when a Wollok project is created, the wizard never ends. After Wollok is restarted, the project is created, but it isn't able to execute it by REPL. It never finished initializing.

I tested it using oracle JDK 1.8.101 and 1.8.102 and Openjdk-8. I checked using jconsole which VM was used in each execution.

I tested it using 3 different PC with similar characteristic. (I attach Hardware info), but another students reported to me the same issue on their personal computers, using Ubuntu 16.04.

Wollok was able to execute correctly under windows 7 OS in the same computers.

I checked the eclipse log. I found exceptions, but I am not sure if they are relevant.

I attach 2 screenshots of Wollok: It is creating a project and it is executing a wlk file by REPL .

Additional Info: output of OS console. OpenJDK 64-Bit Server VM warning: ignoring option PermSize=64M; support was removed in 8.0 OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=128M; support was removed in 8.0 log4j:WARN No appenders could be found for logger (org.eclipse.xtext.ui.internal.Activator). log4j:WARN Please initialize the log4j system properly.

Have you tried another Eclipse without wollok? I found the same issue and is caused by GTK3.

Take a look at this post

You can fix it by adding the following line at wollok.ini

--launcher.GTK_version
2

A student tested it and works, but it's important the order of lines. I copy the response of student. I would recommend to write it into wollok installation page.

"Hola! si funciona pero no es simplemente agregar esas lineas, hay que agregarlas por el medio. Aviso importante:

Solo funciona si abren desde el ejecutable wollok y no ellauncher

el contenido final del wollok.ini es este:

-startup plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar --launcher.library plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.300.v20150602-1417 --launcher.GTK_version 2 -vmargs -XX:PermSize=64M -XX:MaxPermSize=128M"
