Description Michael Nazarov 2009-10-23 07:57:35 UTC 
Some times uninstaller throws NPE. Have no complete steps to
reproduce yet, so P2.

Comment 2 dlipin 2009-10-23 09:06:36 UTC 
Is it reproducible with Sun`s JDK not OpenJDK which uninstaller ran on?
Could you please try to update OpenJDK to the latest version? 1.6.0_0-b12 can be not the latest build.
Comment 3 dlipin 2009-10-23 09:08:01 UTC 
I don`t see why this random issue is P2 so downgrading to P3.

Comment 4 Michael Nazarov 2009-10-23 09:09:38 UTC 
It looks bit random so unfortunately I can't reproduce it so fast and easy.

using steps describe at Bug 178290 I've reproduced it 2 times of 4 attempts
Comment 7 dlipin 2009-12-08 06:23:02 UTC 
Jindrich,

could you please try to reproduce it with 6.8 RC and dev builds?
Thanks.

NPE reproduced in dev build

I'm able to reproduce it in dev build. I needed 5 attempts to get it. It seems to be caused by some concurrency. Try running unninstaller in paraller with some intensive disk activity (for example NB build) to increase the probablity of NPE occurence
Comment 9 dlipin 2009-12-10 05:55:02 UTC 
Could you please try the latest daily build? I add more logging to find out the reason

Thanks,
Dmitry

As I see it's not so random and not fixed for sure.
