Description Jaroslav Pospisil 2004-09-09 15:07:24 UTC

Build 200409071800

1.Run IDE with new userdir
2.Create a new Java application
3.Close it
4.Delete it outside the IDE 
5.Create new java application with the same name
6.EXCEPTION
See attachment.

Notice: Steps 3 to 5 must occur immediately,if
not,variety of different exceptions appear in the log.

java.io.FileNotFoundException

Comment 2 Milan Kubec 2004-09-09 15:32:27 UTC

Don't you have space in the project path or in your userdir path?

Comment 3 Milan Kubec 2004-09-09 15:44:35 UTC

exc stack trace

Comment 4 Milan Kubec 2004-09-09 15:45:41 UTC

Attached second exception that was thown. 

Easily reproducible with clean userdir.

Comment 5 Jan Becicka 2004-09-09 15:49:28 UTC

Wow - this one is P1? :))))

Comment 6 Milan Kubec 2004-09-09 15:52:28 UTC

Regression, it's easily reproducible and the product going out is Beta2!

Doesn't seem to be reproducible on trunk build.

Comment 7 Milan Kubec 2004-09-09 15:58:25 UTC

Moreover this is the only way how user can delete unwanted project -
close it in IDE and delete from disk by some system utility. So you
might consider it also as broken functionality.

Comment 8 Milan Kubec 2004-09-09 16:09:24 UTC

I've just reproduced it in trunk build.

Comment 9 Tomas Zezula 2004-09-09 16:31:16 UTC

Exception 1)
DefaultClassPathProvider calls FileObject.isValid () before trying to
handle the file. But it seems that the file is deleted after the test.
The only what I can do is catch this Exception and recver from it.

Exception 2)
The same problem DefaultClassPathProvider caled with valid FileObject
which root becomes invalid before the classpath is created.

The only question is why the DefaultClassPathProvider is contacted
when the project is closed. This seems to be problem of javacore.
Adding them on CC.

Comment 10 Jesse Glick 2004-09-09 16:40:41 UTC

Probably a bug in javacore - why should it be asking for the classpath
of a file that no longer exists?

However it is strange that FileObject.isValid returns true before. For
debugging, try

if (!file.isValid ()) {
    return null;
}
// added:
File f = FileUtil.toFile(file);
assert f == null || f.exists() : "MasterFileObject.isValid() wrong?";

Comment 11 Tomas Zezula 2004-09-09 16:52:33 UTC

Adding Radek to CC. FO.isValid should do refresh on file to detect
that the file is already deleted.

Comment 12 rmatous 2004-09-09 16:58:06 UTC

Created attachment 17530 [details]
isValid reimplemented

Comment 13 Tomas Zezula 2004-09-09 17:16:05 UTC

I am not able to reproduce it on my Linux, I will try it on Windows to
be able to test fixed FO.isValid (). It will probably help.
In addition to this I can catch FileNotFoundException and return null
ClassPath.
Decreasing priority to P2.

Comment 14 Tomas Zezula 2004-09-09 18:10:25 UTC

The issue is not easy to reproduce even on Windows.

Comment 15 Tomas Zezula 2004-09-09 18:28:33 UTC

It seems that the Radek's patch helped.
I've tried it 20 times and I didn't got FileNotFoundException.
But I've found a deadlock in the javacore:

Comment 16 Tomas Zezula 2004-09-09 18:31:24 UTC

We will integrate the Radek's fix and add the catching of
FileNotFoundException in the DefaultClassPathProvider to fix the
ClassPath and FS related problems. Then I will reassign this issue to
javacore to fix the deadlock

Comment 17 Jesse Glick 2004-09-09 18:48:13 UTC

Better to file a separate issue about the deadlock, to avoid confusion.

Comment 18 Tomas Zezula 2004-09-10 08:08:50 UTC

I've entered new issue for the deadlock above:
