Summary
-------

Change the default value of the Windows-specific property `jdk.io.File.enableADS` from `false` to `true` thereby permitting by default certain characters in Windows file paths in `java.io`.

Problem
-------

The default value of the `jdk.io.File.enableADS` system property is currently `false` which breaks some applications which depend on being able to use certain characters in Windows file paths.

Solution
--------

Change the default value of the `jdk.io.File.enableADS` system property from `false` to `true`.

Specification
-------------

There is no visible specification change.
