Java SE 7!

Download Excelsior JET 9 Now

New And Noteworthy

Support for Java SE 7

Java SE 7 Update 40 is supported out of the box, later updates will be supported through add-ons, as usual.

New Platform

Linux x64 is added to the list of supported platforms.

Other improvements

Stack trace printing is now enabled by default, so as to improve the de-facto compatibility with other Java implementations.

New And Improved in The 64-bit Version

  • Linux support
  • 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.

Still Missing in The 64-bit Version

  • More compiler optimizations
  • Startup Optimizer and Startup Accelerator
  • Global Optimizer, and hence Java Runtime Slim-Down
  • Generation of trial versions

Also, Excelsior Installer is available in the 64‑bit Linux version starting from 9.0 Maintenance Pack 2.

We do intend to port all these features over.

Looking for the 64-bit trials?

As some important features are missing in the 64-bit version, we recommend that you evaluate the 32-bit one unless:

  • Your application requires a large heap,
  • You need to integrate it with 64-bit native libraries, or
  • You need it to run on 64-bit-only systems

Okay, got it, now just show me the download links

At last, we have caught up with Oracle in terms of Java version support, but this race will never end — Java 8 is scheduled for March 2014!

Here are the major items from our to-do list:

  • Support Java 8 on all platforms shortly after it becomes available
  • Add important optimizations and x86 support to the new AOT compiler
  • Port the remaining delayed features to the new compiler
