AdoptOpenJDK jdk15 hotspot 15.0.2.7

Install Java 15 on a Windows computer with the OpenJDK HotSpot virtual machine, giving Java applications the runtime they need to execute. AdoptOpenJDK jdk15 hotspot 15.0.2.7 is a System Tools package from AdoptOpenJDK, and its current version is 15.0.2.700. It supplies prebuilt OpenJDK binaries and targets Windows users who need this particular Java package and its optional installation components.

The MSI package includes FeatureMain for the core runtime, FeatureEnvironment for adding Java to the PATH environment variable, and FeatureJarFileRunWith for opening JAR files through Java; these three components are selected by default. FeatureJavaHome can set JAVA_HOME, while FeatureIcedTeaWeb adds the IcedTea-Web component for compatible web-start applications. FeatureJNLPFileRunWith connects JNLP files with IcedTea-Web, and FeatureOracleJavaSoft writes JavaSoft registry keys beneath the local machine registry.

Installation can be tuned through MSI parameters: INSTALLLEVEL stages the addition of JAVA_HOME, IcedTea-Web, and JNLP associations across levels one through three. INSTALLDIR chooses the destination folder, must be used together with FeatureMain, and otherwise places the package in the system Program Files directory under AdoptOpenJDK. Quiet MSI operation is supported, including unattended setups that modify PATH, associate JAR files, and define JAVA_HOME.

It suits developers, administrators, and users running Java software that depends on OpenJDK 15 or HotSpot-specific behavior. The package is classified as freeware, although its license entry is marked unknown.
