Developer release for 64-bit Intel Itanium processors

The Windows/Linux release is intended only for developers as they begin to work with the IA-64 architecture. It is offered without support and is not for use in production systems or for redistribution with applications.

Applications run only in interpreted mode. Java Plug-in and Java Web Start products are not available in the IA-64 release for Linux and Windows.

Note that the 32 bit versions of J2SE 1.4.1 will not work on Itanium machines.

Java Virtual Machine

Two new garbage collectors have been added to improve application performance:

Concurrent Mark and Sweep Collector. This collector executes mostly concurrently with the application. It trades the utilization of processing power that would otherwise be available to the application for shorter garbage collection pause times.

Parallel Garbage Collector. This collector enables garbage collection to occur on multiple threads for better performance on multiprocessor machines.

Java Plug-in

Several significant enhancements have been made.

An update panel has been added for downloading security patches, in a compact format, as they become available. The Control Panel has been updated with new documentation in the Java Plug-in Developer Guide. Applet startup performance has been improved. Many other improvements have also been made.

Java Web Start 1.2

Version 1.4.1 of the Java 2 SDK and Java Runtime Environment include the new Java Web Start 1.2 product. Java Web Start technology enables deployment of full-featured applications over the net. Version 1.2 offers several significant enhancements requested by the growing number of Java Web Start users.

To use Java Web Start on previous Java releases, download the JRE package for the Java 2 Platform, Standard Edition, version 1.4.1.
