New Excelsior JET 3.7 Focuses on J2SE 5.0 and Parallelism

Excelsior JET 3.7 enables software developers to improve performance and hinder decompilation of their Java applications by converting them into optimized native executables running directly on hardware. This release focuses on J2SE 5.0 API support, parallel execution on multi-CPU systems and code performance improvements.

Novosibirsk, Russia (PRWEB) March 24, 2005 - Excelsior, LLC, a Russian vendor of software development tools, has announced today the general availability of the latest edition of its flagship product, Excelsior JET 3.7. Designed to improve performance and hinder reverse engineering of Java applications through ahead-of-time (AOT) compilation, Excelsior JET now supports the latest version 5.0 of the J2SE API, and its new runtime library is optimized for execution on parallel hardware.

About Ahead-Of-Time Java Compilation

Ahead-Of-Time (AOT) compilation, the distinctive core feature of Excelsior JET, enables developers to maximize performance of their Java applications by transforming them into conventional binary executables that run directly on hardware. At the same time, Excelsior JET fully supports Java dynamic class loading facilities through provision of a redistributable Just-In-Time (JIT) compiler, so it is a complete Java Virtual Machine implementation.

A nice side effect of AOT compilation is the application's improved resistance to reverse engineering, achieved without the performance penalties inherent to Java bytecode obfuscation.

New in Excelsior JET 3.7

Based on customer feedback, support for J2SE 5.0 API enhancements is the most anticipated feature in Excelsior JET 3.7.

Excelsior engineers have also made numerous achievements in application performance over the previous version, particularly in string handling and data processing involving 64-bit operations, such as encryption.

Excelsior JET 3.7, Professional Edition introduces a new runtime library that is optimized for parallel execution. It enables concurrent memory-intensive applications, such as Java servers, to fully utilize the computing power of today's multiprocessor systems and the upcoming dual-core chips.

"Historically, we have been positioning Excelsior JET as a solution for acceleration and protection of desktop applications and low-end Java servers," said Dmitry Leskov, Excelsior's Director of Marketing. "But our customers have discovered that it may be used, with much success, to improve the throughput of their large-scale enterprise Java applications, and demanded better support for high-performing multiprocessor hardware."

The new Excelsior JET runtime library is available in three flavors tuned for different application types and hardware configurations:

The Desktop Runtime is optimized for use in applications typically running on conventional desktop and notebook computers, such as rich clients.

The Workstation Runtime is best suited for technical client applications such as visualization and engineering design, which often run on high-end workstations.

The Server Runtime enables highly concurrent server-side applications to make the most of multi-CPU servers.

The runtime library found in the previous versions of Excelsior JET is also available under the name of Classic Runtime.
