i guess only one process can be killed at a time. or we keep holding the file's io streams when we should not..

Comment 9 Petr Hejl 2010-03-23 11:51:32 UTC 
This is quite strange issue as it seems the OS is reporting it is locked by another process (and NetBeans lives in one process). Messages from exc. reporter are kind of "netbeans start" or "resume on hibernate". Perhaps windows lock survives some time even if the process is dead.

Not P2. 

Anyone is able to reproduce this?
Comment 10 katsuke 2010-03-26 14:39:23 UTC 
Am getting this same error on a very specific condition: 

Have NetBeans IDE 6.8 (Build 200912041610) open, then try to open NetBeans IDE Dev (Build 201003250201) right at the start of the second instance the error is triggered.

When the second instance of NetBeans opens apparently tries to gain access to winp.dll, but since there is another instance of NetBeans running, it kind of makes sense that its being blocked doesn't it?

I tried opening 2 instances of the same version and it doesn't allow me. So i would guess that this issue happens cause opening two different versions of NetBeans at the same time.

(If this description doesn't relate to the issue feel free to delete it)

Fixed in web-main adc8a80e06bb.

katsuke can you verify once it is in dev build? Note that you should use two instances newer than adc8a80e06bb to really test the problem and solution (although one old and and one instance containing fix should work fine as well).

Integrated into 'main-golden', will be available in build *201004020200* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
