Description

RawLocalFileSystem does not work well with symbolic links on Windows. Specifically, calling FileSystem#lengh on the path that is a symlink will return zero. This causes problems in some objects that use LocalFileSystem to access local files. One example is a SequenceFile.

The issue is caused by Java6 File#length returning zero for symbolic links on Windows. On Java7, we will no longer have this problem.
