Description Scott Stark 2001-12-07 05:30:07 UTC 
NetBeans IDE, Release 3.3 Beta 5 (Build 200111201425).
This is similar to issue 17716, but since the stack trace is different,
and it occurs everytime I switch projects I'm opening a seperate bug. On 
switching projects I receive an expection dialog that contained the following 
exception detail information:


*********** Exception occurred ************

Comment 1 Peter Zavadsky 2001-12-07 13:53:53 UTC 
Reassigning to window system. The problem seems to be in ModeData
(line 946), which should probably check if the file exists already.
Comment 2 Scott Stark 2001-12-08 05:17:18 UTC 
I just downloaded 3.3RC1 and I do not see this issue. I am able to 
switch projects without problems.
Comment 3 David Simonek 2001-12-11 10:11:50 UTC 
Hi Scott, thanks for your report. This issue is now fixed for sure,
although I can't find original bug which was fixed. Problem was that
winsys tried to create files which were too long or contained
non-allowed 'strange' chars. 
"java.io.IOException: Cannot create a file when that file already
exists" was a little bit incorrect here, but pointed out that file
cannot be physically created on the disk.
This happened usually when user opened some "explore from here" or
"right click properties" types of windows.

Resolved for 3.4.x or earlier, no new info since then -> verified.
Comment 5 Quality Engineering 2003-07-01 16:44:39 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
