Request for change in JDK6 - proper ISO-8859-15 charset handling

[Pavel Tisnovsky]

Hi,

please review change in JDK6 which provides correct relationship between 
ISO-8859-1 and ISO-8859-15 charsets. The webrew is available at:
http://cr.openjdk.java.net/~ptisnovs/ISO-8859-15/

This bug was closed and verified in JDK7 
(http://bugs.sun.com/view_bug.do?bug_id=6798572) but not in JDK6, where 
the sources are a bit different.

The correct/incorrect behaviour of charset relationship handling can be 
tested by regression test java/nio/charset/Charset/Contains.java

Cheers
Pavel Tisnovsky
