Description Marian Mirilovic 2004-09-03 07:37:34 UTC 
[nb_dev](20040902120), [jdk1.5.0](b63)

Last few days (2-3) I've seen a lot of
FileNotFoundExceptions in messages.log files from
our tests. I don't have exact steps to reproduce,
because is hard to specifiy when expception rises,
but it seems like it happens during test :
Refresh folder with 50-100 java files
- open project 
- create package "x.folder50javafiles" (externally)
- refresh package "x" in projects view
- expand package "x.folder50javafiles" in projects
view
- copy 50/100 java files to the folder
"folder50javafiles" (externally)
- push "Refresh folder " from popup menu over 
"x.folder50javafiles" node in projects view
- measure time 
- collapse "x.folder50javafiles"
- delete "x.folder50javafiles"
- refresh "x" folder

- repeat whole test 5 times

I saw this problems on all our performance test
machines : JDS2, LinuxRH9, Win2K, WinXP, Sol9

See attachments , I think the root off all next
exceptions is FileNotFoundException in first
attachment.

Seems to me that invalid FileObjects are used. Thus probably
appropriate java.io.File already doesn't exist for such FileObject and
all method calls must somehow fail. All attached stack traces comes
from mdr.

So, reassigned for next evaluation.

Changing comp->java/javacore
Comment 7 Jan Becicka 2004-09-03 15:40:55 UTC 
I fixed first exception. I hope other exception will not occur after
this fix. Reopen this issue if the fix does not help.

Checking in RepositoryUpdater.java;
