Found the problem with the different behavior between NT and Unix

[Arieh Markel <Ar...@central.sun.com>]

The problem is manifested in the inability of Tomcat to serve files.

The reason for that inability is caused by the following:

	. the canonical path for a file may have a different
	  representation from that of the real path for the same file

	  
For example, assume the file to be served is:

Its realpath is returned as:

   C:\Program Files\Sun Microsystems\StorEdge\etc\opt\SUNWesm\www\console

Its canonical path is returned as:

   C:\PROGRA~1\SUNMIC~1\StorEdge\etc\opt\SUNWesm\www\console
 
   
Which results on the function that compares (DefaultServlet on 3.1 -
util/FileUtil on 3.2) to not be able to return the file.


The type of fix that I am proposing to have is that if the 
real-canonical comparison fails, to give another try with the conversion
of the appopriate portions of the canonical to the 8.3 format.

(Does anybody have a Java method to generate the appropriate 'tilde'
conversions of longer-than-9 directory/file names ?).

Has anybody ran into similar issues ?

Thanks,

Arieh
