has shipped Excelsior JET 5.0
, introducing Java Runtime Slim-Down, a new deployment model that may help significantly reduce the download size of Java SE applications.
The key new feature of Excelsior JET 5.0
is the ability to exclude certain parts of the Java SE platform from the application's installation package, thus reducing its download size and disk footprint. For example, it may cut down a medium-size Java application that does not use Swing or AWT to a mere 5 MB, whereas the Sun JRE 5.0 alone is a 15 MB download.
When you build an installer for your optimized application, Excelsior JET
automatically creates a secondary package containing the detached Java SE components. You place that package on a Web server accessible to your end users, at the URL you have specified in the primary package containing the application. If the application attempts to access a detached component, the runtime will download and unpack the secondary package.
This release also delivers a major performance improvement over the previous versions. As measured with two standard benchmark suites
(SciMark2 and SPEC JVM98), the composite scores have improved by a factor of 1.7 compared to Excelsior JET 4.x.
No runtime fees apply to applications designed to run on general purpose personal computers and servers, but deployment to embedded systems and devices is subject to royalties.
