Typo.
Don't let exceptions pass through the MSG layer.
Fix java examples: catch exceptions on failures.
Change message to debug loglevel.

Fix javadoc warnings.
Update documentation about java bindings.

use our xbt_getline on every platform to ease our cmake mess

Also, as stdio.h is not loaded by root headers of the simgrid tree, we
need to explicitely load it in some locations.
Further cleanup in the ignore file

- ignore the files touched to track dependencies around java examples
- don't ignore the files for the gras tutorial, as there is no such
  tutorial anymore
