That is what I try to do but this is the same problem than for the “Bottin des jeux Linux”:

Actually, they are even more exigent with Java games. The author of this “Bottin” (huge list of games for Linux) wrote that when he launches a Java game, he loses the control of his machine and he cannot stop the process lol.
