RFR(XXS): 8145212: ISO-8859-1 isn't properly handled as 'fastEncoding' in jni_util.c

[Volker Simonis]

Hi,

could somebody please review this trivial fix:

http://cr.openjdk.java.net/~simonis/webrevs/2015/8145212/
https://bugs.openjdk.java.net/browse/JDK-8145212

The current code only recognizes "8859_1", "ISO8859_1" and "ISO8859-1"
as iso88591 but on Linux, AIX and potentially other OSs a call to
setlocale(LC_CTYPE, NULL) returns the more standard conformant name
"ISO-8859-1".

Notice that this change will trigger "8145015: jni_GetStringCritical
asserts for empty strings" [1] on Linux with an ISO-8859-1 locale if
running any AWT code. So I think the best would be to push this fix
directly to jdk9/hs-rt right after the fix for 8145015 has landed
there. What do you think?

Thank you and best regards,
Volker
