That's right. You've provided no scheme, and so have a
scheme-independent path, a kind of relative path.
On the other hand if I create a file and call its toURI method
I get a scheme.
Right, the scheme is known here, since it comes from a File.
If I try to create a URI without a scheme, the code
errors out for not being an absolute path.
I don't see that demonstrated in your code. One can easily create URIs
without a scheme. You try to create a File from a URI whose scheme is
not "file", which is an error.

My question here is shouldn't the Path toURI method always return the
full path with the scheme?
Where would the scheme come from? If you want a scheme-qualified path,
and have a scheme, you can do this in various ways. For example, to
default to the scheme of the default configured FileSystem, you'd:
Configuration conf = new Configuration();
FileSystem fs = FileSystem.get(conf);
Path p = new Path("/home/dennis").makeQualified(fs);
or to hardwire the local filesystem, you could use any one of:
Path p = new Path("file", "", "/home/dennis");
Path p = new Path("file://" + "/home/dennis");
Path p = new Path("file:///", "/home/dennis");
The current behavior causes problems on
local file system handling code, such as search servers in Nutch.
Can you elaborate?
