Description rudyment 2012-11-29 11:12:42 UTC 
Product Version = NetBeans IDE 7.2 (Build 201207171143)
Operating System = Windows 7 version 6.1 running on amd64
Java; VM; Vendor = 1.7.0_09
Runtime = Java HotSpot(TM) 64-Bit Server VM 23.5-b02

I dowloaded a set of filed from the FTP server.
However the downloading program (WinSCP 5.1.1 build 2735) set to the all downloaded files the date/time 1970-01-01 - 01:00:00).
NetBeans don't want to show content of such files (see the attached screenshot).
After changing the file dates/times the editor started to work.

It looks the files are corrupted. Did you open files with other editors?

> It looks the files are corrupted. Did you open files with other editors?

I was first wondered what happen and so 
I opened the file with another editor (PSPad).
When i discovered that it is readable, 
I opened the Total Commander and set the file date to today.
Then everything started to work.

So i tried to set to date of a file to 1.1.1970 01:00
in TotalCommander by hand
and problems with editihg this file in NB again appeared.

I am afraid that NB don't like, 
when the date/file field of file is set to zero.

JEdit opened the file without problems,
so it seems that it is not a Java problem.
Comment 6 Milutin Kristofic 2012-12-03 13:02:27 UTC 
Reproducible

touch -d 'Jan 1 1970 1:00:00' JavaApplication1.java


I got same as it is in the screenshot above.

I can open file with Notepad.jar.

Comment 7 Miloslav Metelka 2012-12-05 12:44:54 UTC 
When CloneableEditorSupport.loadDocument() calls 

InputStream is = new BufferedInputStream(cesEnv().inputStream());

the MultiDataObject.getFile() returns a file that has file.isValid() == false.
This is likely due to impl of FileObj.isValid():


    @Override
    public boolean isValid() {
        //0 - because java.io.File.lastModififed returns 0 for not existing files        
        boolean retval = getLastModified() != 0;
        //assert checkCacheState(retval, getFileName().getFile());
        return retval && super.isValid();
    }

Reassigning to filesystems.
Comment 8 Jaroslav Tulach 2012-12-06 09:34:22 UTC 
Sad result of using getLastModified() to check if the file exists or not. Anyway this is not the case to optimize for and the fix is easy. Making P4.
