Why is Oracle Java available only for Mac OS X 10.7.3 and above? The Java Runtime depends on the availability of an Application programming interface (API).

OS Type Mac Java Runtime Environment for Mac (JRE for Mac) lets you play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, simply to mention a couple.

Well, not completely, since a mic can be used by any app also Java as long as it is system default. Again, a typical example is permission to use the microphone.Д¬omparing Java and Reaper, Java does not ask any such permissions anywhere, which means all Java Apps are completely stuck until this is fixed. It means the Reaper user does not need to think about it after accepting these requests in Apple System Preferences security. Reaper DAW, one observes that Reaper community has grasped this rule so that Reaper is requesting permission everywhere. But, if the app request an input device NOT currently set as default input, then this is rejected by Big Sur, and there is no audio stream sent to the java App.Д¬omparing Java behaviour to other non-java apps like e.g. In consequence, and as an example: If a java app requests DEFAULT audio input device (often the built in mic, but sometimes virtual sound cards like e.g.

The API Specification of the Java Platform, Standard Edition and Java Development KitД®xcellent tutorial, but as it seems there is a major error in ALL Java JDK and JRE versions around when it comes to Big Sur, as follows:ДЄny application now need permission to access system resources, but Java JDK/JRE does not pose such request, nor is this available as an API for a Java application (?). The source code of the Java Platform, Standard Edition 11 Reference Implementations binaries is available under the GPLv2 in a single zip file. Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home Anyway, open a new terminal and verify: echo $JAVA_HOME In previous macOS versions, this was done in ~/.bash_profile. In ~/.zshrc, I set the variable like so: export JAVA_HOME=$(/usr/libexec/java_home) Here is a trick that allows me to keep the environment variable current, even after a Java Update was installed. JAVA_HOME is an important environment variable and itвЂ™s important to get it right. OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.9+11, mixed mode) OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.9+11)

вЂ¦ hopefully showing something like this: openjdk 11.0.9 After opening a terminal, the successful installation of the JDK can be confirmed like so: java -version Select macOS and ењ†4 and download the JDK (about 190 MB), which will put the OpenJDK11U-jdk_ењ†4_mac_hotspot_11.0.9_11.pkg file into your ~/Downloads folderД¬licking on the pkg file willВ install into this location: /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdkДЄlmost done.

However, the easiest way is to select OpenJDK 11 (LTS), the HotSpot JVM, and macOS ењ†4 is to get the latest release here:

Easy to follow details about how to install OpenJDK are available here. As IвЂ™m writing this, Java 11.0.9 is the latest LTS (Long Term Support) version and AdoptOpenJDKВ isВ one of the best places to find Prebuilt OpenJDK Binaries. Since OS X 10.7 Java is not (pre-)installed anymore, letвЂ™s fix that.
