Turn off code formatting for certain lines in Eclipse 3.6+

Often, we do not want eclipse to auto-format some lines. In Eclipse 3.6+ you can turn off code formatting:

• Preferences -> Java ->  Code Style -> Formatter
• Create your own profile if you have not done it yet: New... 
• Edit your profile, in the Off/On Tags, Enable Off/On Tags

Now in the source code you can

   // @format off
   ... ... ..
   // @format on
