*** Issue 57720 has been marked as a duplicate of this issue. ***

I am not able to reproduce this issue in current builds from release 4.1 branch
(build #200504142205; Java 1.4.2_05 VM 1.4.2-38; Mac OS X 10.3.8).

There is no known way how to reproduce. Many fixes has gone into related source
code since beta. I think this issue can be closed. 

But don't hasitate to reopen it if you are able to reproduce on one of the
latest builds. Thanks.

Perhaps, you can reproduce this error, if you install netbeans in any network path. Our workstation use 
a server for data store. I think netbeans 4.1 has problem with file description, so you get than at start 
error dialog and an IOException in log-file.

Error Dialog

I tested 4.1 RC1 again and found the way to reproduce the error. I get allways an error if my path for 
settings was too large like this: /Network/Servers/cubus.crosssoft.de/Volumes/cubedata/CS/GmbH/
User/dschultheis/.netbeans/4.1rc/ 
If I start netbeans as local user then I don't have any Exceptions.

I have no problem to start NB4.1 RC1 build from following remote location (Sun
Sparc with Solaris OS):
/mnt/MY_SERVER/dashboard/netbeans/Servers/cubuss.crosssoft.de/Volumes/cubedata/CS/netbeans/4.1/netbeans/
with userdir:
/mnt/MY_SERVER/dashboard/netbeans/Servers/cubuss.crosssoft.de/Volumes/cubedata/CS/GmBH/User/dshultheis/.netbeans/4.1rc

I tried even the case when the userdir has invalid permittion. Then I got the
following exception to the console and the IDE doesn't start:
java.io.IOException: Permission denied
        at java.io.UnixFileSystem.createFileExclusively(Native Method)
        at java.io.File.createNewFile(File.java:828)
        at org.netbeans.CLIHandler.initialize(CLIHandler.java:440)
        at org.netbeans.CLIHandler.initialize(CLIHandler.java:280)
        at org.netbeans.Main.execute(Main.java:158)
        at org.netbeans.Main.main(Main.java:39)

So I was not successfull with reproducing of this issue. Could you please
provide additional information about the server OS, FileSystem type and attach
the complete ide.log.

Thanks

Log-File of Netbeans 4.1 RC1

Here is an additional Information about our Server:
Mac OS X 10.3.8
Filesystem: HFS
The complete Log-File I have attached to this issue. If I start netbeans 4.1 RC1 so I can't edit any File 
with him. Only if I start it localy I can edit something. By the same install of netbeans 4.0 we didn't have 
any problem. 

I wonder if the issue is about network path or long path. Could you try creating
a local path that is as long as the network one, preferably with the path items
like "cubus.crosssoft.de" (meaining the dots in path)?

I tried to use netbeans with another location (/Users/cubus.crosssoft.de/blabla/blabla/abrakadabra/.../
aplication/netbeans). It works if the setting-Location is local. How can I change the Setting-Location of 
netbeans (.netbeans)?

Did you try to start NetBeans with -userdir switch? Settings are then stored in
the folder that follows the -userdir parameter. The example of command is:
netbeans.exe -userdir C:\my_userdir -jdkhome D:\j2sdk1.5.0

By starting of netbeans with -userdir /Localpath/../blabla it work properly. But if I open a Project from 
network path like this: /private/Network/Servers/cubus.crosssoft.de/Volumes/cubedata/CS/GmbH/
User/dschultheis/Workspace/Project1 then I get an Error in Log-File Bad-Filedescription and I can't edit 
Project anyway.

Just to add a few comments:
I converted my samba shares to NFS shares in order to avoid the 'bug', so that I can return to actual 
work... But I found out that the same 'bug' is affecting NFS shares too as I was unable to create a new 
project (or work on existing projects) on NFS shares as well. I am not sure whose bug is it and where 
the error lies, but there is a sense of urgency that I feel :-))) as I can't do any work on any networked 
drive...
What exactly is the bug/error/incompatibility here? Can I do something to help speed things up?

We are, of course, talking about MacOSX as the only affected OS.
I am running:
MacOSX 10.4 'Tiger'
Netbeans 4.1RC2
Java SDK 1.4.2_07
on
Dual Processor G5 with 1 GB ram

Because this problem isn't bug in NB (see attachment), we can do a very little
for you, because  its hard to imagine whatever could be improved in NB 4.1. 

For next release we can provide some special property that would ensure that no
nio.FileLocks will be exploited. We could also consider to deliver patch with
this property for NB4.1 users.

java.io.IOException: Operation not supported

Similar issue (reported on Win2000) #57690.

Thanks.
I understand that the Netbeans code is not doing anything wrong/buggy.
I have filed a bug report with Apple, together with sample code and output.

Here is a Linux report regarding file locking issues: 
http://lists.samba.org/archive/samba/2004-October/093732.html
http://lists.samba.org/archive/linux-cifs-client/2004-October/000418.html

Here is also an advisory from Sun:
http://java.sun.com/j2se/1.4.2/docs/api/java/nio/channels/FileLock.html

And we of course have the Win2000 case from the bug report #57690

I don't know what the resolution could be as I am not well versed in IO problems, but it just feels like 
this methodology of file locking needs to be reevaluated when network drives are in question. A great 
number of developers are required to deal with company SMB/NFS/Netware shares.

Thanks for your comment - I plan to reevaluate it ASAP to get rid of these
problems. 

What is with netbeans 4.1 Realease? This Filelocking "feature" is not fixed in release. What is about release 
notes? How can we use the netbeans 4.1? 

The issue remains in NetBeans 4.1 release. We have recommendation how to use
this release and avoid the issue.
The simple workaround is to copy module .jar file from NetBeans release 4.0
(netbeans/platform4/modules/org-netbeans-modules-masterfs.jar)
and paste it to release 4.1 build into the directory
netbeans/platform5/modules/
Filelocking feature is missing then of course.
I replaced the masterfs module and everything works fine when working with
project on remote server (accessed by samba). 

Seeing this when starting Netbeans 4.1 IDE on MacOSX 10.3.9.
This did not occur in Netbeans 4.0

My home directory is imported over NFS.  An existing project in my home directory still opens; 
creating/saving/opening other projects does not I managed to create a new project on the local disk in 
/tmp/ ; having closed it , I can't reopen it.  [This stuff is probably mostly a second bug, but the NFS 
problem seems to be real]

Works fine in trunk build from 2005/07/11.

Sorry for ignorance; how do I get the 'fixed' version of 4.1 or the fixes patch? What is the 'release41_fixes' 
branch and when does it become part of the official 4.1 release on the web page?
Thanks.
