> JdbTest can get exception before jdb field is initialized.
> As Jdb logging does not depend on the instance, made Jdb.log method static

Alex Menkov has updated the pull request incrementally with one additional commit since the last revision:

  Updated accordingly feedback
  
  - made Jdb.log instance private method (I'd prefer to keep the method as a single point to logging);
  - updated JdbTest to use System.out.println directly.
