Arduino 1.5 does not start on Java 7

After updating to OSX 10.9.2 Mavericks and also update to Java 7 64 bit the Arduino app does not start any longer.
$ java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

When I try to start it the icon flash up in the dock but nothing else happens. Further on no useful messages appears in log - just:
30.03.14 12:36:48,231 com.apple.launchd.peruser.501[279]: (cc.arduino.Arduino.86448[1902]) Exited with code: 1

To solve the problem I have to reinstall Java 1.6. An forum post in the Microchip forum give some further information about the installation.
