Run-time profiling focuses compilation effort only on "hot" methods.Compiler interface supporting parallel compilations.System-specific runtime routines generated at VM startup time.Dynamic deoptimization and aggressive compiler optimizations.Accurate generational and compacting garbage collection.Preemptive multithreading based on native threads.Interpreted, compiled, and native frames all use the same stack.It is written in a high-level, object-oriented style, and features: It delivers the optimal performance for Java applications using many advanced techniques, incorporating a state-of-the-art memory model, garbage collector, and adaptive optimizer. The Java HotSpot Virtual Machine is Sun's VM for the Java platform. Advanced Reliability, Availability and Serviceability (RAS) features provide enterprise-grade reliability while enabling rapid development, introspection, and management. Multithreading support throughout the VM yields high scalability on even the largest computing systems available today. An architecture supporting dynamic, object-oriented optimizations enables world-class performance.
The Java HotSpot VM builds on a strong foundation of features and capabilities. Java HotSpot VM - Built on a Solid Foundation
Java HotSpot Server VM, which is designed for maximum program execution speed for applications running in a server environment.Java HotSpot Client VM, which is tuned for best performance when running applications in a client environment by reducing application start-up time and memory footprint.The Java Standard Edition Platform contains two implementations of the Java VM: These improvements are applicable to both the client- and server-side Java VM environments. is also driving performance improvements through the use of various industry standard and internally developed benchmarks. Application server vendors, such as the Sun Java System Application Server, BEA Systems' WebLogic software, IBM's WebSphere software, Apple Computer, Inc.'s WebObjects software, and others.Integrated development environments (IDEs) including the Sun Java Studio Tools, the NetBeans open source project, IBM's Eclipse, IntelliJ IDEA, Oracle JDeveloper, and others.The Java HotSpot VM supports virtually all aspects of development, deployment, and management of corporate applications, and is used by: In addition to new features, this version is upward compatible with previous releases. The Java HotSpot VM builds upon Java technology's cross-platform support and robust security model with new features and capabilities for scalability, quality, and performance. It is the underlying foundation for deploying Web page applets, Web services, large commercial applications, and more. With millions of developers and users, the Java platform is growing explosively in many dimensions: from credit cards to wireless devices, desktops to mainframes.
#ATLAUNCHER JAVA HOTSPOT VM SOFTWARE#
The Java platform has become a mainstream vehicle for software development and deployment. Java SE technology is available for the Solaris Operating Environment (OE), Linux, and Microsoft Windows, as well as other platforms through Java technology licensees. Java HotSpot technology provides the foundation for the Java SE platform, the premier solution for rapidly developing and deploying business-critical desktop and enterprise applications. The Java HotSpot™ virtual machine implementation (Java HotSpot™ VM) is Sun Microsystems, Inc.'s high-performance VM for the Java platform.
