Affects Version/s: 4.3.1.Beta2
Component/s: upstream
Labels:
None

Steps to Reproduce:

Hide

1. In JBoss Central, search for the kitchensink project. There are different variants. I wanted just plain "kitchensink" which was on the 4th page I think.
2. Click the kitchensink, set up an EAP server if not present and create the project
3. In Project Explorer, go and expand the various items in the project tree. Click around.
4. Check the error view - there will be NPEs

I came across this while testing ~~JBIDE-20802~~ .

When I create the kitchensink project from JBoss Central and then click around in the Project Explorer, I will get errors in the error view and workspace log:
