Kafka ? :)

Have you set:
  -Djogamp.debug=all
or
  -Djnlp.jogamp.debug=all
?

I assume not, since your trace files does not contain any string starting w/ like:
  NativeLibrary.findLibrary
  JNILibLoaderBase:

Pls do so - this info will give us a clue if a native OpenAL lib loading
attampt happend.

The debug flag will bloat the trace file even more - a lot.

Regardless of the additional requested debug flags ..

Your system is Win7 32bit and the joal native jar contains:
Which OpenAL32.dll etc ..should work on your system.

I see that you use the DEPRECATED JNLPAppletLauncher,
which could cause the problem!

Please use either 'native' JNLP-Applets
or _RECOMMENDED_ the NApplet way as shown on our JOGL applet-test homepage.

The following JOGL/JOAL test uses both, hence will use JNLP-Applets if available:
 <http://jogamp.org/deployment/jogamp-current/jogl-demos/applet-gearsjoal.html>

I will add a version using NApplet later, as described here:
 <http://jogamp.org/deployment/jogamp-current/jogl-applet-runner-newt-gears-normal-napplet.html>

However, it should be pretty easy to modify your html code to use NApplet
_or_ native JNLP-Applets.

Note: NApplet's are supported w/ all JVM's, incl. OpenJDK.

JOGL Applets still get frozen on my machine and I use OpenJDK with Icedtea-web:

Yeah, looks like the stability of that IcedTea plugin varies from person to
person and time to time :(

But one thing for sure, Xerxes can run it fine :)

Joke aside, can you post details of your used distribution
and OpenJDK / IcedTea packages used ?
Then we may have a chance to track something down.

Will run some tests on Wheeze and Kubuntu in a sec ..

It's 'funny' that (A) work, but not (B).

Admitted, (B) is sort of tricky when it comes to mixed code
but is in it's limits of the spec.
(B) does:
 b1 - launch directly into an Applet instance inside a signed JAR
 b2 - tries to get permissions (code signing relevant) .. and fails
 b3 - if it would not have failed, it would have loaded the GLEventListener
      from an unsigned JAR and utilized that.

Note that b1 is still secure, since we don't grab the whole privilege block
for an extended amount of code, only to read properties.

[Will test w/ kubuntu 12.10 soon]

This indicate a problem with the IcedTea plugin, looks like it have timed out or similar issue while downloading the jar.
Thus if the plugin manages to download all jars == application runs fine and if it for some reason time-out then you will hit the bug.
I will investigate further.

How many concurrect web-accesses do the jogamp webserver handle?

Cheers
Xerxes

I have now triaged and isolated the bug to the Hotspot JVM:

Thank you.

I haven't tested this - but it's a fairly good machine (8 cores, 8GB ram,
apache2):
  MaxKeepAliveRequests 100

We don't use prefork or worker now,
so I guess it depends on resources.

Thank you,
While investigating your log my conclusion is that the Gluegen TempJarCache is not yet initialized. The plugin have downloaded the native jars, in this case the plugin already got the jars in its plugin cache (304) but something still prevents the native jar to get extracted into the Gluegen TempJarCache, also the extracted path never gets added to the list of folders where JOAL looks for the unpacked natives. Note that its both the JOAL tool library and the OpenAL library fails to load.

I will investigate the log further and try reproduce this on a windows machine using the same JDK version.

Appreciate your help :)

The latest JogAmp releases can operate without the now deprecated JNLPAppletLauncher, please test a change to your applet html code to look something like this:
