Guys,

I hope this is not too OT for this list but I
am running out of ideas. What could be possibly
be wrong with the following piece of code:

import java.io.File;

public class test {
  public static void main(String[] args) throws Exception {
 File dir = new File(dir);
 dir.mkdir();
 long m = dir.lastModified();
 File subdir = new File(dir, subdir);
 subdir.mkdir();
 while(dir.lastModified() == m) {
   Thread.sleep(1000);
   System.out.print('.');
 }
 subdir.delete();
 dir.delete();
  }
}

To me it seems like the last modified
is not being updated (even if I re-create
the File object) unless the directory
gets touched *outside* the jvm.

Anyone aware of this problem?

cheers

Hi Torsten!

  public static void main(String[] args) throws Exception {
 File dir = new File(dir);
 dir.mkdir();
 long m = dir.lastModified();
 File subdir = new File(dir, subdir);
This might have to do something with the timestamp resolution of the 
filesystem. Not every filesystem have a resolution of milliseconds but 
some higher factor.
It gets ever worse e.g 10ms  for  FAT on create but 2sec for write 
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/setting_and_getting_the_timestamp_of_a_file.asp)

To be cross platform dont expect more than 2sec.

Bad news, isnt it?

PS: After some googling I found it might be worth to collect those 
precision and create a web page with them.

Yeah, Brett already pointed offlist me on that.

Ouch! Hmm... need to think about
what implications this might have
for the jci monitor...

Sounds like a good idea

Thanks

[VOTE] Release Regexp 1.4

[Vadim Gritsenko]

Hi All,

With several recent bugfixes [1,2], and with previous release published almost 
two years ago [3], I think it is a good time to make a next, 1.4 release of the 
Jakarta Regexp.


Please try out current svn (r232390) version [4] and test for any regressions, 
and vote for a release.


My vote is +1.

Thanks,
Vadim
