General description of the release

Main new features:

  • Improved security user experience - The Java Runtime shows the user fewer security dialogs during runtime. For certified MIDlets, full permissions can be granted in one go.
  • Improved installation user experience - The user needs to accept only a single confirmation dialog when installing a MIDlet.
  • Improved MIDlet start-up experience - The Java Runtime displays an instant start-up screen and also loads faster.

How to check the Java release version

To retrieve the Java release version number, use the standard System.getProperty() method:

System.getProperty("microedition.platform");

The returned string reads something like this:

Nokia5800d-1/20.0.012/sw_platform=S60;sw_platform_version=5.0;java_build_version=1.3.4

In the string, java_build_version indicates the Java release version, in this case 1.3.4.
