Comment 2 Tomas Zezula 2012-03-12 15:41:05 UTC 
Seems as a bug in the DataFolder's node, there is no FileObject in the node's Lookup.
I've added more logging (type of node), jet-main 29134623d8d8.

AE when trying to unfold rt.jar in project view -> project ->Libraries-> JDK 1.7
Comment 7 Tomas Zezula 2012-03-26 11:54:42 UTC 
Now it's obvious. Caused by Please Wait.
Comment 8 Tomas Zezula 2012-03-26 13:32:03 UTC 
Thanks Jirko, after nearly 3 hours trying it on different OSs I am able to reproduce it.
Has to be in "reduced tree" as Jesse has written in comment #5 but I've overlooked it.
Comment 9 Tomas Zezula 2012-03-26 14:35:43 UTC 
Fixed jet-main b80e2ffe220d
