Hi,
In Lucene Java the GetCanonicalPath is needed for the following: Java has
the problem that creating a native lock only affects *other* processes from
using the directory. It does not prevent the same process from writing to the
same index directory. Because of that NativeFSLockFactory keeps a static set of
Path names to also ensure locking in the same JVM/process. To make sure that
this locking works we need the "canonical name" of the directory, otherwise it
is not guaranteed that locking really works.
If this is not an issue on windows (if you lock a file, the file lock is
visible to the same process, too), then you won't need that.
