Start an application with the patched version of Java. Check About This Mac -> Displays. Integrated video card should be still active.
These steps are not enough. additionally this should be done also 
(tested on Idea/JEdit and some other applications):
  - All old jdk should be removed
  - The patched jdk should be re/installed
  - The application should be reinstalled and to Info.plist these lines 
should be added:

  - The fix doesn't work for applets, javapanel, javaws, and also with 
applications which are running via command line (./bin/java -jar xxx). 
Not sure that it can be fixed.
  - It also does not work for some bundled applications which contain 
NSSupportsAutomaticGraphicsSwitching in the Info.plist. Netbeans for 
example. This should be investigated. But for now the fix looks fine.
