AdoptOpenJDK builds have the following properties (8u172 as an exampe). Need to investigate which ones should change.

java.specification.vendor = Oracle Corporation
java.vendor = Oracle Corporation
java.vm.specification.vendor = Oracle Corporation
java.vm.vendor = Oracle Corporation

The text was updated successfully, but these errors were encountered:

For OpenJ9 (AdoptOpenJDK 8u181+b13 release build) we get:

java.specification.vendor=Oracle Corporation java.vendor=Eclipse OpenJ9 java.vm.specification.vendor=Oracle Corporation java.vm.vendor=Eclipse OpenJ9 

I get the following list of vendor-related properties:

 java.runtime.name = OpenJDK Runtime Environment java.runtime.version = 11+28 java.specification.name = Java Platform API Specification java.specification.vendor = Oracle Corporation java.specification.version = 11 java.vendor = Oracle Corporation java.vendor.url = http://java.oracle.com/ java.vendor.url.bug = http://bugreport.java.com/bugreport/ java.vendor.version = AdoptOpenJDK java.version = 11 java.version.date = 2018-09-25 java.vm.compressedOopsMode = Zero based java.vm.info = mixed mode java.vm.name = OpenJDK 64-Bit Server VM java.vm.specification.name = Java Virtual Machine Specification java.vm.specification.vendor = Oracle Corporation java.vm.specification.version = 11 java.vm.vendor = Oracle Corporation java.vm.version = 11+28 

IMO the following properties should note AdoptOpenJDK in some form:

• java.vm.name = AdoptOpenJDK OpenJDK 64-Bit Server VM
• java.vm.vendor = AdoptOpenJDK
• java.vendor = AdoptOpenJDK
• java.vendor.url = https://adoptopenjdk.net
• java.vendor.url.bug = https://github.com/AdoptOpenJDK/adoptopenjdk-build/issues

I’m not entirely convinced by a java.vm.name change TBH.

I have a use case to identify the JRE vendor for analytics in my software. It would be great if we can get the java.vendor or java.runtime.name or java.vm.vendor to tell AdoptOpenJDK.
Do you plan to pick this bug in short-term?

It would also be helpful if we can even get the proposed strings for the final properties. We will be able to put some code in our software which allows to stay compatible with AdoptOpenJDK.

With the new versioning infrastructure in Java11 things are much better (even for other vendors)- Here is an example from Zulu:

java.runtime.name = OpenJDK Runtime Environment java.runtime.version = 10+46 java.specification.name = Java Platform API Specification java.specification.vendor = Oracle Corporation java.specification.version = 10 java.vendor = Azul Systems, Inc. java.vendor.url = http://www.azulsystems.com/ java.vendor.url.bug = http://www.azulsystems.com/support/ java.vendor.version = Zulu10.1+11 java.version = 10 java.version.date = 2018-03-20 java.vm.compressedOopsMode = 32-bit java.vm.info = mixed mode java.vm.name = OpenJDK 64-Bit Server VM java.vm.specification.name = Java Virtual Machine Specification java.vm.specification.vendor = Oracle Corporation java.vm.specification.version = 10 java.vm.vendor = Azul Systems, Inc. java.vm.version = 10+46 

Note especially the java.vendor.version which is not present in 8.

Java SE Overview

There are two principal products in the Java SE platform family: Java SE Runtime Environment (JRE) and Java Development Kit (JDK).

The Java Runtime Environment (JRE) 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 Java Web Start, which deploys standalone applications over a network. It is also the foundation for the technologies in the Java 2 Platform, Enterprise Edition (J2EE) for enterprise software development and deployment. The JRE does not contain tools and utilities such as compilers or debuggers for developing applets and applications.

The JDK is a superset of the JRE, and contains everything that is in the JRE, plus tools such as the compilers and debuggers necessary for developing applets and applications. The conceptual diagram above illustrates all the component technologies in Java SE platform and how they fit together.

The Java SE application programming interface (API) defines the manner by which an applet or application can make requests to and use the functionality available in the compiled Java SE class libraries. (The Java SE class libraries are also part of the Java SE platform.)

The Java SE API consists of core technologies, Desktop (or client) technologies, and other technologies.

• Core components provide essential functionality for writing powerful enterprise-worthy programs in key areas such as database access, security, remote method invocation (RMI), and communications.
• Desktop components add a full range of features to help build applications that provide a rich user experience deployment products such as Java Plug-in, component modeling APIs such as JavaBeans, and a graphical user interface.
• Other components round out the functionality.

The Java Virtual Machine is responsible for the hardware- and operating system-independence of the Java SE platform, the small size of compiled code (bytecodes), and platform security.

The Java SE platform works with an array of tools, including Integrated Development Environments (IDEs), performance and testing tools, and performance monitoring tools.
