Sun's Project Tiger has matured and resulted in the release of the JavaTM 2 Platform Standard Edition (J2SETM platform) Version 5.0, Beta 2. Accompanying the release was news of the latest benchmark results for the solution, which show it as capable of delivering 59,648 JBB operations per second on the SPECjbb 2000 on a 64-bit two-way system.

"Java technology has built a commanding lead in the network computing arena with undisputed popularity and demand among developers," said Jeff Jackson, vice president of Java Developer Platform and Strategy at Sun. "With over 110 million downloads of J2SE since its availability in December 1998, the Java platform continues to fuel the Java economy and drive global business innovation on desktops and servers."

The SPECjbb 2000 benchmark results were achieved running JavaTM Development Kit (JDKTM) 5.0 on a 2.4 GHz Sun FireTM V20z server, based on AMD 64 Opteron processors. The 64-bit two-way system beat the best previously announced 64-bit two-way system results by nine percent. In addition, the tests indicate Sun has the capacity to support more warehouses than any other two-way system, having demonstrated the ability to support 80 warehouses -- 10 times the number typically run on a two-way system.

The new J2SE 5.0 technology delivers more than 100 new features, including language updates, generics, enumerated types, metadata and autoboxing. Other performance improvements in the new release include reduced startup time, a smaller memory footprint and auto-tuning to deliver optimized performance on various computer systems right out-of-the-box.

The platform also features a new monitoring and management API that enables tools to monitor the health of a running JavaTM virtual machine (JVMTM)* remotely or for applications to perform self monitoring for higher levels of reliability, availability and serviceability. Also new in the J2SE 5.0 platform is the Java Management Extensions (JMX) technology, which provides a simple, standard way of managing Java resources such as applications, devices and services.

In addition, the solution has been given an updated, more modern, cross-platform look and feel. Support for advanced graphics hardware acceleration via Sun OpenGLR enables higher levels of Java 2DTM API performance, while a new Pack200 utility dramatically reduces the download size of applets and applications for faster access. User security has been simplified and modified to improve safety.

Sun reported that the JavaTM Specification Request will guide the next platform release, which will include increasingly sophisticated support for XML and Web Services, along with enhanced monitoring and management features, building on J2SE 5.0 features. The team also is evaluating features to simplify enterprise desktop development and deployment.

* Note: The terms "Java virtual machine" and "JVM" mean a virtual machine for the JavaTM platform.
