Description sviyer 2005-10-07 02:28:00 UTC

I get a log of the following when editing an xml ant build file.

Where can I download daily buids for NB 5.0 ? I know where for NB4.1 but can't
find url for NB 5.0 daily buiilds.

Note that I am using NB 5.0 Beta.

Comment 1 sviyer 2005-10-07 02:50:27 UTC

every time I save the file I get a whole lot of assertion error in the log file

Comment 2 Jan Lahoda 2005-10-07 10:54:30 UTC

What kind of project do you use (standard J2SE project, freeform project, etc.)?

Comment 3 Jan Lahoda 2005-11-24 09:27:32 UTC

*** Issue 67878 has been marked as a duplicate of this issue. ***

Comment 4 Milos Kleint 2007-08-02 10:03:23 UTC

either ant/project or ant/freeform related only, not general projects issue.

Comment 5 Jesse Glick 2007-08-02 21:09:06 UTC

NPE is issue #65235, long since fixed, and unrelated to the AE's. Reporter: next time please file distinct exceptions
separately, as it is easier to track that way.

Comment 6 Milan Kubec 2007-09-17 15:39:54 UTC

I did some editing of build.xml but I'm not able to reproduce this problem, since it was reported long time ago and it's
probably related to different NPE that was already fixed, I'm closing this issue as worksforme. If you can still
reproduce, please provide steps how and reopen. Thanks.

Comment 7 Jesse Glick 2007-09-17 16:55:10 UTC

The AE is probably a race condition somewhere that I would not expect to be able to reproduce. I don't think it is
related to the NPE since the AE, but not the NPE, is found in issue #67878.

Comment 8 Jesse Glick 2007-09-17 16:57:13 UTC

Generally I think it is not OK to close bugs from assertions without making some change:

- fixing an actual problem

- improving the assertion message to include more information so you could get further the next time

- commenting out the assertion message, or changing to a logged warning, if the condition seems harmless

Comment 9 Lukas Hasik 2008-04-10 21:24:27 UTC

moving opened issues from TM <= 6.1 to TM=Dev

Comment 10 Milan Kubec 2008-06-20 15:08:42 UTC

Making it duplicate of issue with more up to date stack trace.

*** This issue has been marked as a duplicate of 128134 ***
