In addition, the source code for the last release, 8u66, is available by cloning the 8u master forest : and using the 'jdk8u66-b17' mercurial tag. The corresponding master forest jdk8u can be cloned using this command: hg clone cd jdk8u sh get_source.sh. The jdk8u-dev forest for ongoing development can be cloned using this command: hg clone cd jdk8u-dev sh get_source.sh. The Java JRE is not aware of the resource limit you have set, and will try (and fail) to grab as much of the system memory as is free.

It also states how to download the source code: On all platforms, the JDK comes with an implementation of the Java virtual machine called the Java HotSpot Server VM(server VM). When running an RCE Powered Application - for example an RCE Shell - you have the opportunity to reserve a requested amount of system memory. The JVM passes bytecode to the Graal compiler, which. At runtime, the application is loaded and executed normally on the JVM. GraalVM is based on Java HotSpot VM, but integrates an advanced just-in-time (JIT) compiler, written in Java - the Graal compiler. Here you can find the current OpenJDK 8 (which includes the HotSpot JVM). Any JVM-based application that runs on Java HotSpot VM can run on GraalVM. If you are interested in the source code, OpenJDK is the way to go.
If you are interested in a little more info on this, have a look at the SO question Differences between Oracle JDK and Open JDK While this explaination is not really perfect, it may be good enough to understand that there is no big difference between Oracle JDK and OpenJDK.

On Ubuntu for example you can install this OpenJDK (current version 8) by running sudo apt-get install openjdk8.
OpenJDK is the open source project maintaining and impelmenting the HotSpot JVM, but also many other projects beside the JVM such as Graal or VisualVM.

This is "the typical JVM you will find on a normal user's windows machine". Oracle's JDK can be downloaded on oracle's website, currently. It is available as a binary release for every major operating system and CPU architecture from the tiny Raspberry Pi Zero all the way up to big iron servers containing hundreds of CPU cores and terabytes of RAM. Technical Details Java SE Java HotSpot VM Java HotSpot VM Options Please note that this page only applies to JDK 7 and earlier releases. It is used in both, Oracle JDK and OpenJDK. The HotSpot JVM is an amazing and flexible piece of technology. HotSpot is the most used implementation of the JVM concept. There are multiple different implementations out there, all implementing the Java Virtual Machine Specification The JVM is the underlying runtime that executes java bytecode.
Where should I bind the LwjglCanvas.stop(), should I add it to the EventDispatchThread queue or should I bind it to the JFrame.This SO question may clear up your questions regarding "What is JVM, Hotspot and OpenJDK". Double click on the launcher file to run it. Note that you may need to call stop() or a Swing application may deadlock on System.exit due to how LWJGL and/or Swing deal with shutdown hooks. Once download is completed place launcher to preferred location (in folder). This is slightly less efficient then a dedicated thread, but greatly simplifies synchronization. According to LwjglCanvas docs:Īll OpenGL calls are done on the EDT. I don't know what it means and it's not doing me any harm. However everytime I close the application, this logs to my console:ĪL lib: alc_cleanup: 1 device not closed. Then set the JFrame's default operation on close to EXIT_ON_CLOSE. I tried making one myself, I created a JFrame then added the LwjglCanvas. He used the LwjglCanvas to integrate with Java's Swing. I came across Aurelien Ribon's app that creates rigid Box2D bodies. I've used LwjglApplication for creating some simple apps that render boxes, some meshes and some textures.
I'm trying to engage myself into the Libgdx OpenGL framework.
