[EDIT:] I first wrote it would affect OpenJDK 7, but I realized I have Oracle’s JDK 7 b 147 (Release Candidate) from http://jdk7.java.net/download.html installed [/EDIT]
Hi
I can run Mythruna from OpenJDK6’s JRE without problems. Console output starts with
then Mythruna aborts with generating an error file named "-error.log containing
Uncaught exception from thread:Thread[LWJGL Renderer Thread,5,main]
java.lang.UnsatisfiedLinkError: Can't load library: /opt/Mythruna/liblwjgl.so

(Warnung = warning, translated from german ;) )
Other Java-based applications (Eclipse, RSSOwl, JDownloader and others) run without problems.
// EDIT:
Using Ubuntu Linux 2.6.38 on x86-64 on Core i5 with iGPU
The file "/opt/Mythruna/liblwjgl.so" does not exist.
This is entirely a JME issue. I don’t do anything with that file. It’s supposed to be extracted from the jme jars when they run, I guess… maybe it isn’t being done in this case or somehow incompatible with the platform.
Maybe it’s a permission problem :roll:? Anyway another strange behavior the output showed :“WARNUNG: Cannot locate native library: linux/libbulletjme.so” in both cases.
The jbullet thing has been there a while now and is harmless. For some reason, even apps that don’t use jbullet at all see this warning since some update way back.
Its strange… If there is any exception when copying it should be reported in the console. I would say the best way is to debug the Natives class and see if that file is actually opened and written to.
Ok, JMonkeyPlatform has a similar problem starting with Oracle JDK7:
On startup it shows a note:
Warning - could not install some modules: jME3 Code Checks - The module Java Hints was requested in implementation version "4" but only "7" was found.
I had the choice to disable the module or exit JMP. I disabled the module and JMP started. JMP's status bar shows an error, "show details" shows this Exception:

// EDIT: tested with most recent JMP with all updates installed except those from nightly builds @glaucomardano: I was unable to find it. Where is it? @pspeed: yes, looks like an JME issue. should I report in Forum "Troubleshooting | General" or can this topic be moved there? @glaucomardano: this is no permission problem, since i garanted read and write access to all subfolders of /opt (even before extracting Mythruna)
OpenJDK reports different system names than the normal JDK, thus the system cannot be determined properly and the libraries are not extracted. As stated jME3 requires the default JDK, support for OpdnJDK/Java7 has to be evaluated first.
Don’t know if that’s related to Mythruna. When I start JMonkeyPlatform Alpha-4 I can see msg “Opening SceneViewer” and it hangs at 14% + there is red error right of it. Error says:

This issue is very often, i guess it's a bad graphic card driver or it isn't able to support opengl 2. Try updating it to the lastest graphic card driver.
It’s somewhere in the JME internals.
