Help verifying bug in javax.sound.sampled playback on 10.5.1 with java 1.5.0_13-119

Would someone kindly try reproducing an audio problem I'm hearing on 10.5.1 with java 1.5.0_13-119? Basically when playing back an 8kHz 16- bit PCM audio I hear a weird "robotic" effect overlaid on the audio. This only happens when run under the 1.5 JVM not the 1.4 JVM.

Step:

1) Create the source file $TEST/c/v/TestAudio.java whose contents are attached below.
(where $TEST is some directory of your choice).

2) cd $TEST

3) compile the code:
/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Commands/ javac -source 1.4 c/v/TestAudio.java

4) try running under the 1.5 JVM:
/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Commands/ java c.v.TestAudio http://www.nch.com.au/acm/8k16bitpcm.wav


Do you hear weird "robotic" static over the top of the audio clip?


5) Note if you run under the 1.4 JVM and it sounds fine:
/System/Library/Frameworks/JavaVM.framework/Versions/1.4/Commands/ java c.v.TestAudio http://www.nch.com.au/acm/8k16bitpcm.wav

If its not specific to my system I'll report it to Apple

Thanks,

Eric

        ais.close();
