* src/java/org/classpath/icedtea/pulseaudio/PulseAudioMixer.java
(getLine): Throw the exception with a more meaningful description.
* src/java/org/classpath/icedtea/pulseaudio/PulseAudioTargetDataLine.java
(drain): Implemented drain. Blocks while the TargetDataLine remains started.
* unittests/org/classpath/icedtea/pulseaudio/PulseAudioTargetDataLineTest.java
(testIsActiveAndIsOpen): Fixed thinko. Now tests a TargetDataLine instead
of a SourceDataLine.
(testDrain): New function. Tests if drain() blocks between calls to
start() and stop().
(testStartedStopped): Removed call to drain. Instead wait a bit.
(tearDown): Clean up a bit more if possible.
