I am pretty sure Java applications do not use a sound server, but access ALSA libary directly. Phonon maintainers know better.

kde services

I notice that "sound policy" is not running in kde services. I don't kwon if it matters.

No it does not matter, well, not particularly, though it should be running REALLY.

Anyhow, the issue is with Java hogging your output device, which eliminates awesomeness. That said, you should be using PulseAudio to prevent this from happening. AFAIK Java can integrate with PulseAudio, just like any other reasonable software, thus rendering this a non-issue at Phonon level. (not that we could do anything about broken software mixing anyway)
