OpenAL and FloatBuffer problem

I'm copying the sample code almost exactly but I'm having a problem. When trying to set any sort of position I get the following error:

java.lang.IllegalArgumentException: Number of remaining buffer elements is 0, must be at least 1
   at org.lwjgl.BufferChecks.checkBufferSize(BufferChecks.java:177)
   at org.lwjgl.BufferChecks.checkBuffer(BufferChecks.java:197)
   at org.lwjgl.openal.AL10.alListener(AL10.java:1014)

Here's the code where its failing:

FloatBuffer sourcePos = BufferUtils.createFloatBuffer(3).put(new float[] { 0.0f, 0.0f, 0.0f });

/** Velocity of the source sound. */
FloatBuffer sourceVel = BufferUtils.createFloatBuffer(3).put(new float[] { 0.0f, 0.0f, 0.0f });

/** Position of the listener. */
FloatBuffer listenerPos = BufferUtils.createFloatBuffer(3).put(new float[] { 0.0f, 0.0f, 0.0f });

/** Velocity of the listener. */
FloatBuffer listenerVel = BufferUtils.createFloatBuffer(3).put(new float[] { 0.0f, 0.0f, 0.0f });

/** Orientation of the listener. (first 3 elements are "at", second 3 are "up") */
FloatBuffer listenerOri =
BufferUtils.createFloatBuffer(6).put(new float[] { 0.0f, 0.0f, -1.0f, 0.0f, 1.0f, 0.0f });

public void play3DSound(Sound sound, Vector3F sourcePosition, Vector3F sourceVelocityScaledDirection)
{

AL10.alListener(AL10.AL_POSITION, listenerPos); //FAILS
AL10.alListener(AL10.AL_VELOCITY, listenerVel); //FAILS
AL10.alListener(AL10.AL_ORIENTATION, listenerOri); //FAILS

AL10.alSourcei(sound.getAlSourceID(), AL10.AL_BUFFER, sound.getAlSoundID());
AL10.alSourcef(sound.getAlSourceID(), AL10.AL_PITCH, 1.0f );
AL10.alSourcef(sound.getAlSourceID(), AL10.AL_GAIN, 1.0f );
AL10.alSource (sound.getAlSourceID(), AL10.AL_POSITION, sourcePos ); //FAILS
AL10.alSource (sound.getAlSourceID(), AL10.AL_VELOCITY, sourceVel ); //FAILS

AL10.alSourcePlay(sound.getAlSourceID());
}

All of the lines marked //FAIL above will fail if put first with that buffer error. What am I doing wrong??? I've tried in 0.95 and 0.96 with the same result. Its like its expecting there to be 4 elements for each vector., but if I set the size of the buffers to 4, the error goes away but the sound doesnt' work. Please help!
