The whole time is spent in java.io.FileOutputStream.close0[native]() it seems the io is somehow unable to cope. The possible reason can maybe be the incessant logging of following exception and even printing of whole source files into log - see the messages.log. Maybe the fix of the exception will fix the io issue... reassigning to java/navigation for evaluation.

Comment 3 Tomas Zezula 2013-06-24 12:04:49 UTC 
In reply to comment #2: I doubt so. No printing of tree is done, the stack trace is short. Also the data are already "written" (probably in cache). The close does not force write back. The File.sync() is required for write back.

The exception itself is a duplicate of issue #231104.
