RFR 8170900: Issue with FilePermission::implies for wildcard flag(-)

[Wang Weijun]

An clarification is added to FilePermission::implies:

      * @implNote
        ....
      * a simple {@code npath} is recursively inside a wildcard {@code npath}
      * if and only if {@code simple_npath.relativize(wildcard_npath)}
-     * is a series of one or more "..". An invalid {@code FilePermission} does
+     * is a series of one or more "..". Note that this means "/-" does not
+     * imply "foo". An invalid {@code FilePermission} does
      * not imply any object except for itself.

The newly added sentence is

  Note that this means "/-" does not imply "foo".

JCK has agreed to update their test.

Since this is just a clarification inside an @implNote and no spec is updated, 
I suppose no CCC is needed. Please confirm.

Thanks
