Description Petr Nejedly 2005-04-12 13:43:45 UTC 
Calling getNodes() from more concurrent threads on a Children.Keys subclass
can lead to creation of more nodes per each key.

Comment 6 Petr Nejedly 2005-08-11 14:27:27 UTC 
Added a failing test:
openide/nodes/test/unit/src/org/openide/nodes/ChildrenKeysTest.java,v1.2

Reassigning to Yarda, he aggreed to look at it once there is a test.

I'll work on the issue for 4.2, but not now, I have other things to do for 
next few weeks.

Comment 11 Jaroslav Tulach 2005-09-20 12:02:54 UTC 
This fix is not going to be deadlock proof. We can expect few of them in  
future, but as there is nothing much better to do, let's try this:  
  
"#57769: Call to createNodes is synchronized so it is done just once per each 
entry"
