Check out a control suite for managing Java-based projects. Work with the tools for deploying and distributing programs, fixing compatibility issues, and organizing cross-platform elements via generated executables compatible with specific systems. Reduce system loads.
Excelsior JET enables you to distribute and deploy your Java applications as optimized native executables that start and work faster, do not depend on the JRE, and are as difficult to reverse engineer as if they were written in C . The program keeps the size of the Java SE runtime as small as possible, reducing the download size and disk footprint of Java applications.
v7.6 [Sep 29, 2011]
The major new feature introduced in this release is the Startup Accelerator that enables you to reduce the startup time of large Java applications by a factor of 2.
Excelsior JET 7.2 also reduces build time, speeds up JIT compilation and features usability enhancements.
Startup Accelerator
The newly implemented Startup Accelerator can halve the cold startup time of a large Java application. Its usage is as simple as running the application after compilation on the page Finish of the JET Control Panel. This new feature is also supported in automatic builds.
You may find benchmark results, usage guidelines, and FAQ for the startup optimization on this page.
Build Time Reduction
In our last customer survey, long build times firmly occupied the top spot in the list of annoyances.
You complained, we listened. Our tests show that upgrading to version 7.2 should reduce compilation times by at least 30%. Compilation of large Java applications consisting of tens of thousands of classes can be twice as fast now.
As an extra bonus, building install packages with xpack is about 10% faster.
Usability Enhancements
We are sorry it took us so long to fix this. The JET Control Panel and JetPackII projects now reference application files using relative paths, which eases integration of Excelsior JET into automatic builds.
Excelsior JET 7.2 Enterprise Edition includes an Eclipse IDE plug-in that enables you to optimize, protect and package an Eclipse RCP application from within the IDE. For more details, refer to the file
ideplugins/Eclipse/readme.txt
in your Excelsior JET installation directory.
Installation Toolkit Enhancements
During installation, Excelsior Installer now detects if an existing copy of the application being installed is running and prompts the user to close the application first.
Also, if some application files cannot be overwritten, the installer stops gracefully, asking the user to check if they are used by other applications.
Other Improvements
Faster JIT compilation (as usual)
The average JIT compilation time for various scenarios has been reduced by 15%.
Java version support
Java SE 6 Update 20 (1.6.0_20) is supported.
Note: As of Excelsior JET 7.2, support for J2SE 5.0 is no longer provided. If you have not yet moved to Java 6, you have to use Excelsior JET 7.0 or one of the prior versions.
Eclipse version support
Support for Eclipse RCP 3.6 (Helios) is included.
