Hello Shaun,

Thank you to pointing me to the lib libswt-pi-gtk-3116.so. I got that 
installed, and therefor I think, that java  -Xrs -Xdebug 
-jar /usr/share/java/Azureus2.jar was the wrong commandline, because it 
lacks the -Djava.library.path=/usr/lib.

If I start it with that option the error seems to be the same as if I 
start the azureus script (which gives that option).

Can we assume, that the bug is in the Java VM? 
These are my Java packages:
sun-j2re1.5 
Version: 1.5.0+update02
 This package has been automatically created with java-package (0.23).
 sun-j2sdk1.5 
Version: 1.5.0+update02
 This package has been automatically created with java-package (0.23).

So its more likeley, that it's in these packages as then in 
libswt-gtk-3.1or some other related java packages?

Kind regards
