Current b10 Jcov implementation can't reload coverage data
then empty Jcov data file used. To reproduce this bug please
try to do following:

1. Start Jcov Browser GUI.
2. Load non-empty coverage data using 'File' -> 'open jcov data file...'
   menu item.
3. Repeat 2 step using empty jcov data file. This file should be in
   Jcov format:
---------- empty Jcov coverage data file begin -----------
JCOV-DATA-FILE-VERSION: 2.0
---------- empty Jcov coverage data file end -------------
