Comment 2 Maria Tishkova 2014-10-09 11:21:30 UTC 
Looks like the problem was with using virtual box and incorrect port forwarding setup
Comment 3 Maria Tishkova 2014-10-09 11:22:18 UTC 
sorry, wanted to close another bug
Comment 4 Maria Tishkova 2014-10-30 09:42:40 UTC 
Ok. here is my evaluation


The exception occurred as resetConfiguration invoked in one thread in ConfigurationDescriptorProvider which clean auxObjectsMap fro MakeConfiguration and meanwhile in another thread (EDT) debugger is trying to get object from this map (no lock is used for changes in auxObjectsMap in Configuration)
