If you prefer to answer with questions: do server need sound?
Or should awry one who make openstreetmap use other OS? Or there is some
other painless soulution for us?
or you expect i'll fix pulseaudio?
I do my job in OSS community and you probably do your. I reported this
bug to make it pain less for other _users_, awry one who use
ubuntu-server have more knowledge to edit this config then ubunu-desktop
users...

Status in “openjdk-6” package in Ubuntu: New

Bug description:
openjdk-6-jre-headless use alsa by default. This brake things on karmic where pulseaudio is default sound system (choppy sound and more). The fix is simple:
edit /etc/java-6-openjdk/sound.properties and change 

javax.sound.sampled.Clip=com.sun.media.sound.DirectAudioDeviceProvider
javax.sound.sampled.Port=com.sun.media.sound.PortMixerProvider
javax.sound.sampled.SourceDataLine=com.sun.media.sound.DirectAudioDeviceProvider
javax.sound.sampled.TargetDataLine=com.sun.media.sound.DirectAudioDeviceProvider

to

javax.sound.sampled.Clip=org.classpath.icedtea.pulseaudio.PulseAudioMixerProvider
javax.sound.sampled.Port=org.classpath.icedtea.pulseaudio.PulseAudioMixerProvider
javax.sound.sampled.SourceDataLine=org.classpath.icedtea.pulseaudio.PulseAudioMixerProvider
javax.sound.sampled.TargetDataLine=org.classpath.icedtea.pulseaudio.PulseAudioMixerProvider


To reproduce try to use josm (javaopenstreetmap)  and load some sound file... this will brake sound if you press pause and play again. After this fix, every thing working fine.
