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 :
When writing a WAV file with floating-point audio data, the incorrect encoding type for integer PCM data is written to the WAV file header.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
The test program below can be used to copy a floating-point WAV file. The output file written by the program will have the wrong encoding. When the output file is opened with an audio editor, a corrupt audio signal is displayed, because the floating point audio data is interpreted as integer data.


REPRODUCIBILITY :
This bug can be reproduced always.
