JavaDevelopment Kit (JDK) is a comprehensive software development environment specifically designed for Java programming language. Developed by Oracle Corporation, JDK equips developers with all the necessary tools and resources to create, test, and deploy Java applications on various platforms.

The core components of JDK include the Java Runtime Environment (JRE), essential for running Java applications, and the Java Compiler (javac), responsible for translating Java source code into bytecode that can be executed on any Java Virtual Machine (JVM). Furthermore, JDK contains a variety of libraries, APIs, and debugging tools to streamline the development process and ensure high-quality code.

With JDK, developers have the flexibility to build applications for diverse environments, from desktops and servers to mobile devices and embedded systems. It also supports different operating systems, such as Windows, macOS, and various flavors of Linux.

JDK receives regular updates to keep up with the latest Java advancements, enhancing performance, security, and stability. Developers can download JDK for free from the official Oracle website and start exploring the vast Java ecosystem, which includes a myriad of open-source libraries, frameworks, and tools.

In conclusion, Java Development Kit is an indispensable toolkit for developers aiming to harness the power of Java to create robust, platform-independent applications efficiently. Its wide adoption across industries and continuous support from the Java community make it a fundamental choice for programming ventures of all sizes.

The following sections summarize changes made in all Java SE 11.0.18 BPR releases. The BPR releases are listed below in date order, most current BPR first. Note that bug fixes in previous BPRs are also included in the current BPR.

Oracle recommends that the JDK is updated with each Critical Patch Update.In order to determine if a release is the latest, the Security Baseline page canbe used to determine which is the latest version for each release family.

Critical patch updates, which contain security vulnerability fixes, are announced one year in advance onCritical Patch Updates, Security Alerts and Bulletins.It is not recommended that this JDK (version 11.0.18) be used after the next critical patch update scheduledfor April 18, 2023.

With this fix the SunJSSE DTLS implementation will by default exchange cookies for all handshakes (new and resumed) unless the System property jdk.tls.enableDtlsResumeCookie is false. The property only affects the cookie exchange for resumption.

This issue prevents yum from automatically installing the correct packages required by Oracle Linux specific x86_64 headless and headful JDK packages. Instead of x86_64 packages, it will install i686 packages. To workaround the issue, you may manually install packages with the same names as indicated by yum but with the x86_64 architecture.

rpm -qa grep -E -e '^jdk-.*-headful-.*\.x86_64$' -e '^jdk-.*-headless-.*\.x86_64$' xargs -r rpm -q --requires sort -u cut -d ' ' -f 1 grep -v '^rpmlib' xargs -r rpm -q --whatprovides sort -u grep -e '.i[3456]86$' xargs -r rpm -q --queryformat '%name.x86_64\n' xargs -r echo

Communication with the alternatives framework of JDK RPM package has changed. JDK RPM packages of prior versions registered a single java group of commands with the alternatives framework. The JDK 11 RPM package registers java and javac groups with the alternatives framework. java group is for commands used to run applications: java, jjs, keytool, pack200, rmid, rmiregistry, unpack200. javac group is used for all other commands. The set of commands registered by the package has not changed.

Two new Oracle Linux (OL)-specific JDK RPM packages have been added: jdk-11-headless and jdk-11-headful. These packages are available in OL7, OL8, and OL9 repositories. They are not available for OTN downloads. jdk-11-headless is a Headless Java Runtime for running non-GUI applications. jdk-11-headful is a Headful Java Runtime & Development Tools for developing and running applications of all types.

The combination of the OL-specific jdk-11-headless and jdk-11-headful packages provides the same JDK image and the same capabilities as jdk-11 OTN package. OL-specific JDK RPM packages specify required capabilities, and the "Release" property of these packages has a %dist suffix.

Windows JDK installers must install the Oracle JDK in %Program Files%\Java\jdk-%FEATURE% instead of %Program Files%\Java\jdk-%VNUM%. I.e. all updates of the same release must share one installation directory.

If the JDK11.0.19 installer is launched when JDK11.0.18 is already installed, it will auto-upgrade them to JDK11.0.19. There may be a Files In Use dialog shown if the older version was running and locking JDK files.

The Oracle JDK installation directory name will be changed from /Library/Java/JavaVirtualMachines/jdk-$VERSION.jdk to /Library/Java/JavaVirtualMachines/jdk-$FEATURE.jdk. Thus the 11.0.18 and 11.0.19 releases will both install into the /Library/Java/JavaVirtualMachines/jdk-11.jdk installation directory. Installing an older JDK update release will log an error, and not install the JDK, if a newer version of the same feature release already exists. An error dialog will be shown except in the case of a silent installation. JDK 11.0.N update releases shipped prior JEP C208 will not be uninstalled during installation of JDK 11 update release with JEP C208. However, JDK 11 GA release will be removed and its location /Library/Java/JavaVirtualMachines/jdk-11.jdk will be reused.

ProcessBuilder on Windows is restored to address a regression caused by JDK-8250568. Previously, an argument to ProcessBuilder that started with a double-quote and ended with a backslash followed by a double-quote was passed to a command incorrectly and may cause the command to fail. For example the argument "C:\\Program Files\", would be seen by the command with extra double-quotes. This update restores the long standing behavior that does not treat the backslash before the final double-quote specially.

The Set implementation that holds principals and credentials in a JAAS Subject prohibits null elements and any attempt to add, query, or remove a null element will result in a NullPointerException. This is especially important when trying to remove principals or credentials from the subject at the logout phase but they are null because of a previous failed login. Various JDK LoginModule implementations have been fixed to avoid the exception. An Implementation Note has also been added to the logout() method of the LoginModule interface. Developers should verify and if necessary update any custom LoginModule implementations to be compliant with this implementation advice.

If you have issues with a Java application and if you have native or JNI libraries that are compiled with a different release of the compiler, then you must consider compatibility issues between the runtimes. Specifically, your environment is supported only if you follow the Microsoft guidelines when dealing with multiple runtimes.

Specifically, if an application tries to close its SSLEngine inbound side using SSLEngine.closeInbound() without having received a close notification message from its peer, the SSLEngine will no longer:

The new behavior will still consider this condition an error and will throw a local javax.net.ssl.SSLException. But a fatal-level alert will no longer be generated to be sent to the peer, and the underlying session will remain valid.

In addition, the internal transport context for the SSLEngine will also now be closed. This may result in a different SSLEngineResult.HandshakeStatus value on the SSLEngine. Any outstanding outbound data must still be obtained (SSLEngine.wrap()) and sent in order to gracefully close the connection.
