Now you will be able to download JDK 8u using the links given below. To download the latest JDK offline installer full setup, just navigate the official website of Oracle and the get the JDK 8 direct download link for your particular platform.
When you click on the download link of JDK 8, you are asked for Oracle account sign in, if you already have an account, fill up your credentials to login Oracle account.
Older software such as Adobe Photoshop and Illustrator requires legacy Java support. Here are the steps you can take to finally rid yourself of this pop-up:. Download JDK 8u Offline Installer When you click on the download link of JDK 8, you are asked for Oracle account sign in, if you already have an account, fill up your credentials to login Oracle account. Mount the.
The nonstandard package com. The com. It has never been part of the platform specification. In JDK 1. Starting in JDK 9, you can choose to build and run your application against any subset of the modules in the Java runtime image, without needing to rely on predefined profiles. The tools in JDK 8 support three profiles, compact1 , compact2 , and compact3.
In JDK 8, you use the -profile option to specify the profile when running the javac and java commands. JDK 9 and later releases let you choose the modules that are used at compile and run time.
By specifying modules with the new --limit-modules option, you can obtain the same APIs that are in the compact profiles.
This option is supported by both the javac and java commands, as shown in the following examples:. For the compact1 profile: java. For the compact2 profile: java. For the compact3 profile: java. You can use the jdeps tool to do a static analysis of the Java packages that are being used in your source code. This gives you the set of modules that you need to execute your application.
Code that uses locale-sensitive services such as date, time, and number formatting may produce different results with the CLDR locale data. Remember that even System. To enable behavior compatible with JDK 8, set the system property java. Use the jlink tool introduced with JDK 9 to package and deploy dedicated runtimes rather than relying on a pre-installed system JRE.
These technologies have their own methods to manage the JREs needed, by finding or downloading and updating the required JRE, as needed. This makes the launcher's launch-time JRE version selection obsolete. In the previous releases, you could specify what JRE version or range of versions to use when starting an application. Version selection was possible through both a command-line option and manifest entry in the application's JAR file.
The object attribute of the applet tag and the object and java object applet parameter tags are ignored when starting applet. JNLP files let you specify complex comparisons.
Starting in JDK 9, if the element that can be parsed as an int is a shorter string than the other element, it will be padded with leading zeros before being compared lexicographically by ASCII value. This ensures there can be no circularity. In the case where both version comparisons and a JNLP servlet are used, you should use only numeric values to represent versions. This is permitted in the specification. The JNLP specification has been enhanced to add a type attribute to application-desc element, and add the subelement param in application-desc as it already is in applet-desc.
They are included in the JDK and are activated by default. If your country or usage requires a more restrictive policy, the limited Java cryptographic policy files are still available. If you have requirements that are not met by either of the policy files provided by default, then you can customize these policy files to meet your needs.
See the crypto. We recommend that you use the PKCS12 format for your keystores. A low-pause collector such as G1 GC should provide a better overall experience, for most users, than a throughput-oriented collector such as the Parallel GC, which is the JDK 8 default.
The following GC combinations will cause your application to fail to start in JDK 9 and later releases:. The foreground mode for CMS has also been removed. Removed Permanent Generation.
The permanent generation was removed in JDK 8, and the related VM options cause a warning to be printed. You should remove these options from your scripts:. Garbage collection GC logging uses the JVM unified logging framework, and there are some differences between the new and the old logs.
You may also need to update your JVM logging options. All GC-related logging should use the gc tag for example, —Xlog:gc , usually in combination with other tags. The javah tool has been superseded by superior functionality in javac. It was removed in JDK Since JDK 8, javac provides the ability to write native header files at the time that Java source code is compiled, thereby eliminating the need for a separate tool.
It was found in the db directory of the JDK installation directory. The useful features of the hprof agent have been superseded by better alternatives, including some that are included in the JDK. For creating heap dumps in the hprof format, use a diagnostic command jcmd or the jmap tool:. The jhat tool was an experimental, unsupported heap visualization tool added in JDK 6. Superior heap visualizers and analyzers have been available for many years.
The launchers java-rmi. The javax. Upon invocation, all its methods and constructors throw java. UnsupportedOperationException with an explanatory message. Two classes, org. The native2ascii tool has been removed from the JDK. Desktop class contains replacements for the APIs in the Apple—specific com. The APIs in the com. However, they remain accessible at runtime, so existing code that is compiled to old versions continues to run.
Eventually, libraries or applications that use the internal classes in the apple and com. The AppleScript engine, a platform-specific javax. The AppleScript engine has been mostly unusable in recent releases. As of September , the Java Plugin required to launch Applets, remains updated on Windows in Java 8 but may be removed at any time in a future update release.
Oracle Customers can find more information at My. Support Note Pattern class defines character classes in regular expressions with square brackets. For example, [abc] matches a,b , or c. Negated character classes are defined with a caret immediately following the opening square brace. In JDK 8 and earlier, negated character classes did not negate nested character classes. The operators are applied one after another. This behaviour was confusing and difficult to understand.
However, in JDK 9 and later, the negation operator was applied to all nested character classes. As a best practice, look for regular expressions that use character classes with some combination of negation, intersection, and nested classes.
These regular expressions may need to be adjusted to account for the changed behavior. After you have your application working on JDK 11, here are some suggestions that can help you get the most from the Java SE Platform:.
If needed, cross-compile to an older release of the platform using the new -—release flag in the javac tool. Get familiar with new features like multi-release JAR files see jar.

Getting Started The purpose of this guide is to help you identify potential issues and give you suggestions on how to proceed as you migrate your existing Java application to the latest JDK release. Oracle no longer provides a bit Windows download. The removed modules are: java. Policy java. Class,int java. Object java. Java Deployment Tools javapackager javaws Note: pack and unpack have been deprecated and might be removed in a future JDK release.
Lucida Fonts: Oracle JDK no longer ships any fonts and relies entirely on fonts installed on the operating system. Note: Migrating is an iterative process. Update Third-Party Libraries For every tool and third-party library that you use, you may need to have an updated version that supports the latest JDK release.
Compile Your Application if Needed Compiling your code with the latest JDK compiler will ease migration to future releases since the code may depend on APIs and features, which have been identified as problematic.

Updates include: Java Language Enhancement JEP Sealed Classes — Sealed classes and interfaces restrict which other classes or interfaces may extend or implement them. This enhancement is yet another improvement from Project Amber, which aims to increase developer productivity by evolving the Java language.
Starting in Java 1. Those variances are no longer helpful or necessary, so they have been removed by JEP This change improves the interoperability of different PRNGs and makes it easy to request an algorithm based on requirements rather than hard coding a specific implementation.
This port will allow Java applications to run natively on the new Arm based Apple Silicon computers. Being optional, they were already removed from JDK It has not been the primary means of securing client-side Java code for many years, and it has rarely been used to secure server-side code.
Removing it in a future release will eliminate a significant maintenance burden and enable the Java platform to move forward. It will still be possible to access existing internal APIs, but it will now require enumerating, as command-line parameters or JAR-file manifest attributes, each package for which encapsulation should be relaxed.
This change will lead to more secure applications and fewer dependencies on non-standard, internal JDK implementation details. Previews and Incubators for Later JDK Releases JEP Pattern Matching for switch Preview — Allows an expression to be tested against several patterns, each with a specific action, so that complex data-oriented queries can be expressed concisely and safely.
