Description Jesse Glick 2008-06-26 19:06:44 UTC 
Dev build. Trying to deploy JSPWiki. Had some problems with GFv2 admin password, finally got it right (I think!),
pressed F6 on web app again. Build failed:

init:
deps-module-jar:
deps-ear-jar:
deps-jar:
library-inclusion-in-archive:
library-inclusion-in-manifest:
compile:
compile-jsps:
Deployment error:
null
See the server log for details.

Comment 1 Petr Hejl 2008-10-06 15:33:12 UTC 
I'm not aware of any way how to reproduce this. I was looking into the code, but didn't find a way how this could
happen. Jesse do you have any further details? Are you able to reproduce it?
Comment 2 Jesse Glick 2008-11-07 18:06:23 UTC 
Sorry, I don't know, just tried it once (do not usually try to do web app development!) and it failed with this error.
Generally an NPE means you can put in some more descriptive assertion code nearby, though.
Comment 3 Thuy.d Nguyen 2008-12-19 01:16:13 UTC 
Since we do not have a reproducible case for this issue, We'll need to add an assertion to the code to get more info if
it ever happens again.
Comment 4 Petr Hejl 2009-08-06 12:55:59 UTC 
I'm afraid we are not able to reproduce this one.
