FULL PRODUCT VERSION :
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

A DESCRIPTION OF THE PROBLEM :
For WAV files containing floating-point audio data, AudioInputStream.getFrameLength() returns the number of bytes instead of the number of 32-bit sample frames.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the test program below with a WAV file containing floating-point audio data.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
AudioInputStream.getFrameLength() should return the number of sample frames, as it does for WAV files containing integer PCM data.
ACTUAL -
AudioInputStream.getFrameLength() returns the number of bytes, when the WAV file contains floating-point audio data.

REPRODUCIBILITY :
This bug can be reproduced always.
