Public bug reported:

Binary package hint: openjdk-6-jre

Problem: No audio output from applets in firefox using pulseaudio.


charm% lsb_release -rd
Description:    Ubuntu 9.10
Release:        9.10

This bug is in a combination of packages:
 - openjdk-6-jre 6b16-1.6.1-3ubuntu1
 - openjdk-6-jre-lib 6b16-1.6.1-3ubuntu1
 - icedtea6-plugin 6b16-1.6.1-3ubuntu1

Examples:
  - Webex meetings
  - http://www.javazoom.net/applets/tinyplayer/tinyplayer.html

Doing some investigation, I found two things:

 - There is a security policy problem for applets using sound
 - There is a packaging problem with the location of the native pulse library for java

Working backwards using java stacktraces on stderr, I found the following permissions 
were necessary to get audio output from java:

$ cat .java.policy
grant {
  permission java.lang.RuntimePermission 
        "loadLibrary.pulse-java";
  permission java.io.FilePermission 
        "/usr/lib/jvm/java-6-openjdk/jre/lib/ext/i386/libpulse-java.so", "read";
};

Then, I found that the .so file didn't actually exist! Instead, it's in
a different directory:

$ dpkg -L openjdk-6-jre | grep pulse
/usr/lib/jvm/java-6-openjdk/jre/lib/i386/libpulse-java.so

Making a symbolic link fixed everything and made it work:

$ ls -l /usr/lib/jvm/java-6-openjdk/jre/lib/ext/i386
lrwxrwxrwx 1 root root 7 2010-02-22 11:19 /usr/lib/jvm/java-6-openjdk/jre/lib/ext/i386 -> ../i386

I can't say how the policies should be managed for applets, but even
regular java programs aren't likely to work until the packaging is
fixed.
