v10.0 [Aug 6, 2014]
New And Noteworthy
OS X Support
The 64‑bit versions of Excelsior JET, Professional and Enterprise Editions are now available for Apple OS X desktop operating system.
New And Improved in The 64-bit Version
64
OS X support
Application performance improvements evidenced by industry‑standard and popular benchmarks:
SPECjvm2008 and SPECjbb2002 composite scores improved by more than 25%
20% to 60% speedups observed on the DaCapo benchmark suite
etc.
Executable sizes reduced by 15-25%
Benchmark results improved across the board:
Excelsior JET 9 vs 10 benchmarks
Still Missing in The 64-bit Version
More advanced compiler optimizations
Startup Optimizer and Startup Accelerator
Global Optimizer, and hence Java Runtime Slim-Down
Generation of trial versions
We do intend to port all these features over.
Java Version Support
Excelsior JET 10 supports Java SE 7 Update 55. More recent versions will be supported via updates, as usual.
v9.0 [Jan 13, 2014]
- Compilation time reduced by 10% on average
- Compiler memory footprint 3x lower
- Application performance improvements:
- 1.2x improvement of SPECjvm2008 composite score
- 1.6x to 2x higher performance of selected tests from EEMBC and DaCapo benchmark suites.
- Stack trace printing is now enabled by default, so as to improve the de-facto compatibility with other Java implementations.
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.
