PulseAudio capture issue

[jon.vanalten at redhat.com]

Confirmed.

$java -version
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8) (fedora-39.b18.fc12-x86_64)
OpenJDK 64-Bit Server VM (build 14.0-b16, mixed mode)

If com.sun.media.sound provider is specified in sound.properties, this example works fine.  If org.classpath.icedtea.pulseaudio provider is used, exceptions abound.  Fails at different points, giving different exceptions, depending on the output (WAV/AU/etc) chosen.

I went ahead and opened a bug against this.

cheers,

jon
