[14] RFR: 8229960: Remove sun.nio.cs.map system property

[naoto.sato at oracle.com]

Hi,

Please review the fix to the following issue:

https://bugs.openjdk.java.net/browse/JDK-8229960

Here are the links to its CSR and proposed changeset:

https://bugs.openjdk.java.net/browse/JDK-8230405
https://cr.openjdk.java.net/~naoto/8229960/webrev.00/

The subject system property was provided in JDK 1.4.1 for applications 
to help migrate from old Shift_JIS charset definition to IANA charset 
definition. As reported in the bug, it is now partially broken since 
JDK9. Instead of fixing it, we are proposing removing the system 
property as this property should have been removed years ago.
