Created attachment 73800 [details]
Comment 2 Thuy.d Nguyen 2008-12-19 02:19:20 UTC
For us to debug the issue,  could you describe the steps to reproduce this error? At what point in your development
activity, did you get this error?
Comment 3 martinoconnor 2009-03-01 20:19:29 UTC
I can't remember much detail about it, but I was using a maven project.
Comment 4 Petr Hejl 2009-04-02 16:27:30 UTC
Milosi, have you ever seen this?
Comment 5 Milos Kleint 2009-04-02 17:25:31 UTC

the stacktrace attached to the issue doesn't come from maven projects..
what file is null anyway?
Comment 6 Exceptions Reporter 2009-10-24 20:44:53 UTC
This issue already has 22 duplicates 
Comment 7 Petr Jiricka 2011-09-30 09:04:52 UTC
Still happens sometimes in 7.0.x, now 153 duplicates. Reported on the netcat mailing list:
"it happen when creating new java web project."

Comment 8 Petr Hejl 2011-10-03 13:13:44 UTC
This is very hard to reproduce (well, impossible for me). Is there a reproducible use case? Perhaps it might be related to FS permissions and/or project configuration. Does this happen for new ant web project? Or for web project with existing sources?

Comment 11 Petr Hejl 2011-10-07 12:37:47 UTC
I think I found reproducible case. I noticed in sent reports that in every report there is a project deletion followed by a project creation. Reporters can you confirm that?

It looks like the deleted project is actually the source of exception. Although it is deleted its objects are still in memory (not yet GCed) and receive events from the subsequent project creation (same name and location) triggering NPE, IAE etc.

Should be fixed in web-main 27d3ae281d8d. Please verify.

Jirko, as the patch is touching the project listeners, can you also verify there are no regressions in changing the server, changing the WEB-INF and META-INF location? I checked that but it would be great if somebody else could recheck it.
