There is a test data file `
jdk/test/sun/nio/cs/mapping/JIS0212.b2c.private` which contains the following wording:
```
# Recipient is granted the right to make copies in any form for
# internal distribution and to freely use the information supplied
# in the creation of products supporting Unicode. Unicode, Inc.
# specifically excludes the right to re-distribute this file directly
# to third parties or other organizations whether for profit or not.
```
However this mapping file is not used in any of the regression tests, thus it should be removed. Also some other mappings that have `.private` extension are in the same situation. Should be removed too.
