Description kiril mitov CLA 2009-04-02 12:38:47 EDT 
After I have successfully executed smoke test
http://wiki.eclipse.org/WTP_Smoke_Test_Results_R31_040209 without any errors even in the error log
I have deleted the created projects. 
There were 7 projects in the workspace - EJB2.1, WEB2.4, Ear1.4, EJB3.0, EJB3.0, Web2.5, Ear1.5.

On deleting the projects the following error occurs (Full stack trace attached)

Comment 3 Petya Sabeva CLA 2009-05-16 07:20:21 EDT 
This issue is very hard to be investigated, because it is hard to be reproduced. I've tried about 20-25 times to redproduce it, but I can't. The build id of the eclipse, which I use, is I20090430-2300.
Comment 4 Carl Anderson CLA 2009-06-01 22:29:39 EDT 
Moving to 3.1.1 for further investigation.
Comment 5 Carl Anderson CLA 2010-02-04 02:12:49 EST 
As far as I know, this issue has not resurfaced.  If this can be reproduced with WTP 3.2, please reopen this bug.
