Related to my problem :
http://www.jmonkeyengine.com/jmeforum/index.php?topic=10391.0
solved by basixs’ suggestion and using his patch commited here :
http://www.jmonkeyengine.com/jmeforum/index.php?topic=9981.0
I create a path for Jme1.0, to fix the destroy context problem.
I hope any developpers have access to the old CVS to eventually commit it.
In Jme1.0, I don’t find any JoglCanvas or SwtCanvas so I just do a patch for JmeCanvas.java :

I hope you can do it, because it's impossible for me to migrate to Jme2.0 the moment. We have hundred of classes using jme and not enougth time to upgrate them.
Thanks
