Please fix the fs code, the tests, or exclude the tests, but anyway make sure
the stable config does not fail.
Comment 1 rmatous 2001-11-30 13:46:00 UTC 
I`m sorry, but on Win2000 it seems that no test fails. I`ll 
investigate it on Linux and Solaris. I`ll solve it today.
Comment 2 Jesse Glick 2001-11-30 14:20:23 UTC 
Yes, I use Linux (JDK 1.3.1_01). Let me know if you need the complete
logs for the other tests too, and also if you want I can try to run
the tests again to see if they fail reproducibly for me.
Comment 3 rmatous 2001-11-30 17:33:23 UTC 
I did not know that on UNIX is true that:
 1/ new File ("folder").length != 0
 2/ after file "ioFile" is modified: ioFile.lastModified () < 
timeBeforeStartOfWriting

So I modified tests and fixed to relase33. I deleted 
testLastModified .

Then there also fails testRename on Solaris. So, I`ll investigate it. 
But at the moment was this code excluded from stable bag.
Comment 4 Jesse Glick 2001-11-30 18:34:57 UTC 
#2 looks strange, but #1 is quite normal on Unix. Folders contain a
list of files. Normally you are not permitted to read this data
directly, but it does consume some space on disk, typically 1024 bytes
or some multiple of that.
Comment 5 Quality Engineering 2003-07-01 16:05:19 UTC 
Resolved for 3.4.x or earlier, no new info since then -> verified
Comment 6 Quality Engineering 2003-07-01 16:25:05 UTC
