Motivation:
With NIO 2.32.0 we broke the core NIO module up into modules that split
apart the POSIX layer and the core abstractions. As a result, this
package no longer needs to express a hard dependency on the POSIX layer.
Modifications:
- Rewrote imports of NIO to NIOCore.
- Added NIOEmbedded and NIOPosix imports where necessary in tests.
- Extended soundness script to detect NIO imports.
- Note that the main modules still depend on NIO, which is necessary
for backwards-compatibility reasons. This dependency is unused.
Result:
No need to use NIOPosix.
