error log on crash

VirtualGL allows you to remotely login to a Linux machine and get full 3D hardware acceleration.

Since JOGL 2.1.4, JOGL crashes with a fatal error on startup. It all works fine in versions 2.1.3 and before. Below is the console output and attached the error log.

Steps to reproduce:
- Get a Linux machine and install VirtualGL (e.g., sudo apt-get virtualgl, followed by  sudo /opt/VirtualGL/bin/vglserver_config, restart X)
- Get another Linux machine and install VirtualGL
- Log in to the first machine using vglconnect (e.g., /opt/VirtualGL/bin/vglconnect {user}@{server})
- Start a JOGL sample through vglrun, in my case I did: vglrun java -cp jogamp-all-platforms/jar/jogl-all.jar:jogamp-all-platforms/jar/gluegen-rt.jar:jogl-demos/jar/jogl-demos-data.jar:jogl-demos/jar/jogl-demos-util.jar:jogl-demos/jar/jogl-demos.jar demos.gears.Gears


Console output (see attahment for error log):

I get the crash when using versions 2.1.4 and later, up to the current version, using following steps after having set up VirtualGL.

wget http://jogamp.org/deployment/v2.1.4/archive/jogamp-all-platforms.7z
wget http://jogamp.org/deployment/v2.1.4/archive/jogl-demos.7z
7z x jogamp-all-platforms.7z
7z x jogl-demos.7z

Comment 1 Bart Adams 2014-10-03 11:15:43 CEST

My configuration is as follows:
- Ubuntu Linux 12.10
- VirtualGL 64-bit v2.3.2
- NVIDIA GeForce GTX 660 Ti/PCIe/SSE2 (4.4.0 NVIDIA 340.32)
- Java 7 64-bit (1.7.0_45-b18)

Does the crash also happen w/ latest aggregated build ?

+++

I see in the logs that the crash happens during EGL initialization,
i.e. eglInitialize(..).

Hence I assume somewhat VirtualGL is at fault here.

You can also test w/o EGL, via property 'jogl.disable.opengles'
  -Djogl.disable.opengles

Comment 3 Bart Adams 2014-10-06 10:33:11 CEST

Crash also happens with latest aggregate build (Oct 4).

Using -Djogl.disable.opengles works, i.e., it does not crash when running using VirtualGL.

Thanks

This is a bug w/ the VIrtualGL / GL propagation
of using EGL/ES .. not JOGL's fault.

Yes, EGL/ES probing was added after 2.1.4.

Closing -> Invalid.
