segmentations faults at jogamp startup using 0.7 and current git (regression since 0.6+20130401)

[Xerxes Rånby]

I have started to see segmentations faults at startup when testing to use avian in combination with jogamp jogl.
Jogamp examples have worked with avian and openjdk 7 before thus i think it is a regression.
gdb backtrace included below using a mode=debug avian build:

The jogamp testcase pass if I use the 0.6+20130401-0ubuntu1 version of avian that is currently shipping with ubuntu.
sudo apt-get install jvm-7-avian-jre
java -avian -version
java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.12) (7u25-2.3.12-4ubuntu3)
Avian (build 0.6, package 0.6+20130401-0ubuntu1)

Thanks for the report, Xerxes. The segmentation faults are just
NullPointerExceptions (GDB catches them before the VM can turn them into
NPEs). The root problem is that libnativewindow_awt.so can't be loaded,
because it depends on libjawt.so, which depends on libmawt.so, which is
not loaded by default. The VM used to load it during initialization, but
I had to comment-out that code due to another bug:

https://github.com/ReadyTalk/avian/commit/419ac24963bf4008a9491ec17292a0960d74d261

Unfortunately, I don't remember exactly what the bug was. Interestingly,
though, it was committed on the same day I posted to this thread:
https://groups.google.com/forum/#!topic/avian/7EkHYdKmgvI, so maybe I was
actually trying to fix an Ubuntu/OpenJDK/Avian problem then, too.

Anyway, if you revert that commit, the GLWindow example seems to run
successfully. The question now is: When should the VM load mawt and when
should it not? I'm afraid that just reverting that commit will cause some
other problem. Is there a better way to make sure it's loaded when it's
needed than explicitly loading it when the VM is initialized?

[Xerxes Rånby]

Thank you Joel I did not realize it was all related to native library loading, I can help narrow down the issue:

libawt and libmawt are supposed to get loaded by the OpenJDK run-time during
java.awt.Toolkit.getDefaultToolkit()
when running on a -Djava.awt.headless=false platform
libjawt has to get loaded manually for OpenJDK 7 after libawt and libmawt is initialized before the symbols are available to libnativewindow_awt.so

Inside JogAmp we call Toolkit.getDefaultToolkit() and load jawt manually inside the JAWTJNILibLoader's static constructor
we use JAWTJNILibLoader inside JAWTUtil's static constructor.
we use JAWTUtil during NativeWindowFactory static constructor using reflection:

http://jogamp.org/git/?p=jogl.git;a=blob;f=src/nativewindow/classes/jogamp/nativewindow/jawt/JAWTUtil.java#l293
http://jogamp.org/git/?p=jogl.git;a=blob;f=src/nativewindow/classes/jogamp/nativewindow/jawt/JAWTJNILibLoader.java#l50
http://jogamp.org/git/?p=jogl.git;a=blob;f=src/nativewindow/classes/javax/media/nativewindow/NativeWindowFactory.java

libnativewindow_awt is then finally loaded by jogamp when NativeWindowFactory has detected that it is running on a "headfull" awt platform.

JAWTUtil and JAWTJNILibLoader debug output can be enabled using: -Dnativewindow.debug.JAWT=true
NativeWindowFactory debug out is enabled using  -Dnativewindow.debug=true

i compared the library load order order using a patched version of avian and jamvm that prints when System.loadLibrary is called to spot the differences in the static initialization.

it appears that the call to Toolkit.getDefaultToolkit() and the explicit loading of jawt manually inside the JAWTJNILibLoader's static constructor never takes place when using avian.

Thanks for investigating this, Xerxes. I'm sorry I haven't followed up
yet, but I plan to look at it this weekend. My guess is there's something
subtly wrong with how Avian is loading and initializing classes; maybe
it's being too lazy somewhere. I'll let you know what I find.

Thanks again for reporting this. It turned out to be a JIT compiler
optimization gone awry: https://github.com/ReadyTalk/avian/pull/167

With that patch, the JogAmp example seems to run fine on my machine. Let
me know if you see any other issues.
