Chris Nauroth commented on HADOOP-11293:
----------------------------------------
bq. Is there anything we can do to keep this from happening again in the future?
Unfortunately, I think the only thing we can do is put out a reminder to
downstream projects that if they find themselves calling something with a
non-public {{InterfaceAudience}}, then it would be preferable if they filed a
feature request to us for providing a real public, stable API. Otherwise, I
don't see any options for truly strict enforcement.
Project Jigsaw potentially gives us some enhancements on top of the stock Java
visibility modifiers. This would be kind of like {{LimitedPrivate}}, but with
real enforcement provided by the JDK that only the listed callers may call it.
This won't be available to use for a long time though.

> Currently the code that detects the OS type is located in Shell.java. Code
> that need to check OS type refers to Shell, even if no other stuff of Shell
> is needed.
> I am proposing to refactor OSType out to its own class, so to make the
> OSType easier to access and the dependency cleaner.
