Welcome page make openETCS crashed on Ubuntu 14.04 64

[cecilebraun]

The crash happens when opening the welcome page
(bug for @faustco and myself

# A fatal error has been detected by the Java Runtime Environment:
#  SIGSEGV (0xb) at pc=0x00007f2ddcbaebe9, pid=12815, tid=139835796596480

# Problematic frame:

#

The libwebkitgk is known to have some problems with eclipse some fixes are:

• set the environment variable to SWT_GTK3= 1
  -> this is not working for @faustco
• add these two lines at the end of the openETCS.ini

-Dorg.eclipse.swt.browser.DefaultType=mozilla
-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner

-> this makes the welcome page not directly open in the openETCS GUI but with firefox.

Anybody has a better solutions or same troubles ?

[faustco]

This is a screen capture from Eclipse window, when SWT_GTK3= 1
Result may vary depending on previous actions

I just install the las t version of openETCS on linux 64 bits this morning.
I have no troubles, and can access completely to the sysml diagrams.
Same configuration for JRE and libwebkitgtk:

java -version
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

/usr/lib/x86_64-linux-gnu/libwebkitgtk-1.0.so.0
/usr/lib/x86_64-linux-gnu/libwebkitgtk-1.0.so.0.22.10
/usr/lib/x86_64-linux-gnu/libwebkitgtk-3.0.so.0
/usr/lib/x86_64-linux-gnu/libwebkitgtk-3.0.so.0.22.10

[cecilebraun]

I could reproduce the crash with
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

/usr/lib/x86_64-linux-gnu/libwebkitgtk-1.0.so.0
/usr/lib/x86_64-linux-gnu/libwebkitgtk-1.0.so.0.22.10
/usr/lib/x86_64-linux-gnu/libwebkitgtk-3.0.so.0
/usr/lib/x86_64-linux-gnu/libwebkitgtk-3.0.so.0.22.10

on an ubuntu 14.04

[MariellePetitDoche]

I am on xubuntu 14.04

Maybe issue is on another direction...

[jastram]

I did not have this problem, but Eclipse on GTK has been notoriously problematic ever since Ubuntu started their universal menu integration.

@cecilebraun - considering that this only affects a few people, and as there is a workaround, is this really a showstopper? If not, then please remove the label.

Last, this may resolve itself once we migrate to Luna.

[cecilebraun]

I remove the show stopper since we have some workaround.
This should be then tested when moving to Luna.

[MatthieuPERIN]

I have asked our Linux users, Papyrus Linux is tested with enforced GTK version 2.

So if the forced use of GTK 3 have failed please consider installing and forcing GTK 2 as a last chance opportunity.

[MatthieuPERIN]

@faustco any changes ?

[MatthieuPERIN]

As no response propose to close !
@cecilebraun what is your call on that ?

[cecilebraun]

I tried with forcing GTK2 and it's still crash.
I propose to let this open to not forget to try this when moving to Luna.

[MatthieuPERIN]

I think this is not Papyrus related but more Eclipse related.
Cannot guarantee working condition for Eclipse Luna on that point (plus the fact that it seems to work on some linux configuration as @MariellePetitDoche said)

[cecilebraun]

I am sure it is not Papyrus related. We need to find the good linux configuration. Marielle and I have the same config and I can make it crash.
Still need some investigation.

[jastram]

As there is a workaround and few users use Linux, I'll close this.
