-------------------------------------
Yes core runs with assertions enabled. Funny you mention it, I'm running
HDFS-697 (enable asserts) on trunk as we speak.

> A FileStatus may represent a file, directory or symlink. This is indicated
> using the isdir and symlink members, let's add an assert that validates the
> contstraints on these members (eg a directory may not have the symlink member
> set). We could also verify this by having more than one constructor but we
> don't statically know the type of the file status when we create it.
