Hi,
IntelliJ missed me during the vacations and now that I came back it decided to hang while indexing. I'm on OSX 10.9.5 using IntelliJ 14.0.2. I cleaned up caches and index folders and it still keeps hanging. I have to force quit Intellij and when it comes back up it starts to index and when it seems to be done it hangs. Cannot break the loop and I need to work so workarounds or a fix is much appreciated. 
Attached is the log of IntelliJ. Some relevant parts seem to be:
