<Sound Dev> [9] Review Request: 8135088 Typo in AuFileReader

[Sergey Bylokhov]

Hello, Audio Guru.

Please review the fix for jdk9.

Long long time ago support of AU format was implemented with assumption 
to support a few standards:
- ".snd"(official SUN standard)
- "\0ds." (extension DEC)
Also we support both big/little-endian.

But later we removed support of little-endian from the writer in the 
https://bugs.openjdk.java.net/browse/JDK-4297100

And now after a manual code review I found that we actually never 
supported little-endian/DEC, because of the typo in AuFileReader.java

As a fix I suggest to drop support of non standard extensions, and work 
only in case of ".snd" + big-endian.
