As a Java game engine developer, I can say it's still a problem with Java. Sound mixing will work or not depending on people's installed sound system, sound cards, Linux distro, and a plethora of other factors I don't understand (and apparently no one understands, according to forum searches). And yes, I know most of you don't like Java, but this is still a problem that doesn't happen in any other OS (OS X is Unix and handles this fine).
