But strangely the program execution is not coming out of the main thread called. After connecting to the node is it trying to fetch something which never completes?
If you take a thread dump or look at it using VisualVM or so, can you see where it's hanging? Also, have you tried enabling wire logging [1] to see which requests may not be completing?
