Java Runtime Environment (JRE) allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, just to name a few. It’s also integral to the intranet applications and other e-business solutions that are the foundation of corporate computing.
It provides the libraries, the Java Virtual Machine, and other components to run applets and applications written in the Java programming language. In addition, two key deployment technologies are part of the JRE: Java Plug-in, which Enables Applets to Run in Popular Browsers; and Web Start, which deploys standalone applications over a network. Many cross platform applications also require Java to operate properly.
Itis a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. The program is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere! Itis at the heart of digital lifestyle. It’s the platform for launching careers, exploring human-to-digital interfaces, architecting the world’s best applications, and unlocking innovation everywhere—from garages to global organizations.
Why should I upgrade to the latest version?
The latest version contains important enhancements to improve performance, stability and security of the applications that run on your machine. Installing this free update will ensure that your applications continue to run safely and efficiently.
What will I get when I download software?
The Java Runtime Environment 64 bit (JRE) is what you get when you download software. The JRE consists of the Java Virtual Machine (JVM), Java platform core classes, and supporting Java platform libraries. The JRE is the runtime portion of the software, which is all you need to run it in your Web browser.
What is Java Plug-in software?
The program is a component of the (JRE). The JRE allows applets written in the programming language to run inside various internet browsers. The Plug-in software is not a standalone program and cannot be installed separately.
I have heard the terms Virtual Machine and JVM. Is this software?
The Virtual Machine is only one aspect of software that is involved in web interaction. The Java Virtual Machine is built right into your software download and helps run Java apps.
Note: When your installation completes, you may need to restart your browser (close all browser windows and re-open) to enable the installation.

Removed Features and Options
Java DB, also known as Apache Derby, has been removed in this release.
We recommend that you obtain the latest Apache Derby directly from the Apache project at:
JDK-8197871 (not public)
Endpoint identification has been enabled on LDAPS connections.
To improve the robustness of LDAPS (secure LDAP over TLS) connections, endpoint identification algorithms have been enabled by default.
Note that there may be situations where some applications that were previously able to successfully connect to an LDAPS server may no longer be able to do so. Such applications may, if they deem appropriate, disable endpoint identification using a new system property: com.sun.jndi.ldap.object.disableEndpointIdentification .
Define this system property (or set it to true ) to disable endpoint identification algorithms.
New access checks have been added during the object creation phase of deserialization. This should not affect ordinary uses of deserialization. However, reflective frameworks that make use of JDK-internal APIs may be impacted. The new checks can be disabled if necessary by setting the system property jdk.disableSerialConstructorChecks to the value «true». This must be done by adding the argument -Djdk.disableSerialConstructorChecks=true to the Java command line.
The following are some of the notable bug fixes included in this release:
The implementation of VirtualMachineImpl.canGetInstanceInfo() has been corrected, so it is now able to see JDK JVMs >= JDK 9.
This correction allows certain debugger agents to operate correctly without any action required from a user (developer).
A klass that has been cons >ClassLoaderData/SystemDictionary , and its _java_mirror or _class_loader fields can be stored in a root or any other reachable object making it alive again. Whenever a klass is resurrected in this manner, the SATB part of G1 needs to be notified about this, otherwise, the concurrent marking remark phase will erroneously unload that klass.
In this particular crash, while G1 was doing concurrent marking and had prepared its list of unreachable >java_mirror of the loaded classes. G1 did not have knowledge of these thread-local JNIHandles, and in the remark phase, it unloaded the classes per its prior knowledge of unreachable classes. When these JNIHandles were later scanned, it lead to a crash.
This fix for JDK-8187577 informs G1’s SATB that a klass has been resurrected and it should not be unloaded.
A fix included in JDK 8 Update 152 introduced a regression that might cause the HotSpot JVM to crash during startup when the UseNUMA flag is used on Linux systems with versions of libnuma older than 2.0.9. This issue has been resolved.

Java Development Kit 64-bit 8 Update 181
User rating User Rating
Java Development Kit is the official development kit for the Java programming language. Java Development Kit contains the software and tools that you need to compile, debug, and run applets and applications written using the Java programming language.
JDK has a collection of programming tools, including javac, jar, and the archiver, which packages related class libraries into a single JAR file. This tool also helps manage JAR files, javadoc — the documentation generator, which automatically generates documentation from source code comments, jdb — the debugger, jps — the process status tool, which displays process information for current Java processes, javap — the class file disassembler, and other components are also included.
Key Contents include:
- Development Tools (In the bin/ subdirectory) Tools and utilities that will help you develop, execute, debug, and document programs written in the JavaTM programming language.
- Runtime Environment (In the jre/ subdirectory) An implementation of the Java Runtime Environment (JRE) for use by the JDK. The JRE includes a Java Virtual Machine (JVM), class libraries, and other files that support the execution of programs written in the Java programming language.
- Additional Libraries (In the lib/ subdirectory) Additional class libraries and support files required by the development tools.
- Demo Applets and Applications (In the demo/ subdirectory) Examples, with source code, of programming for the Javaplatform. These include examples that use Swing and other Java Foundation Classes, and the Java Platform Debugger Architecture.
- Sample Code (In the sample subdirectory) Samples, with source code, of programming for certain Java API’s.
- C header Files (In the include/ subdirectory) Header files that support native-code programming using the Java Native Interface, the JVM Tool Interface, and other functionality of the Java platform.
- Source Code (In src.zip) Java programming language source files for all classes that make up the Java core API (that is, sources files for the java.*, javax.* and some org.* packages, but not for com.sun.* packages). This source code is provided for informational purposes only, to help developers learn and use the Java programming language. These files do not include platform-specific implementation code and cannot be used to rebuild the class libraries. To extract these file, use any common zip utility. Or, you may use the Jar utility in the JDK’s bin/ directory: jar xvf src.zip.
The JDK also comes with a complete Java Runtime Environment. This consists of a Java Virtual Machine and all of the class libraries present in the production environment, as well as additional libraries, internationalization libraries and the IDL libraries.
