The sun.nio.cs.map system property was removed

The sun.nio.cs.map system property was removed in Java SE 14. This property was originally introduced in Java 1.4 for migration from a Windows definition of 'Shift_JIS' to the IANA definition, but has been broken since Java 9. The property can be replaced with another relevant charset if needed.
