OpenSUSE (armv8)
It is also known to work with Debian (armhf) and Ubuntu (armhf).
Liberica JDK 16 distribution
Liberica JDK 16 are distributed as .rpm, .zip, .deb and .tar.gz packages. Please select the one which is most appropriate for your purposes.
Liberica 16 introduced all new features supported by OpenJDK 16.
With the introduction of the Jigsaw feature in JDK 9 and Minimal VM it is now possible to create a Runtime that is sufficient to run your application and trim down the size of the Runtime. To generate a Runtime with just the Minimal VM, add --vm=minimal to jlink options.
Liberica JDK continues to provide support for AOT and Graal JIT. Since in OpenJDK 16 builds these features are deemed experimental and deprecated, it is recommended to compile native executables with Liberica Native Image Kit to avoid errors.
By default, the Liberica uses Server VM. Server VM and Client VM can be enabled with -server and -client command line options, respectively. In case the deployment requires to minimize the footprint, it may be beneficial to use Minimal VM, which emphasises on a minimal footprint. It has C1 JIT compiler only, Serial GC and no serviceability features.
LibericaFX for the Raspberry Pi
Liberica JDK 16 come with a bundled LibericaFX implementation, which is based on OpenJFX. The following tables lists Java FX modules status of Liberica distribution
-
Java FX Graphics - works.
-
Java FX Controls - works.
-
Java FX Media - does not work.
-
Java FX Webkit - does not work.
The following pipelines are known to work: EGL, SW (direct framebuffer) and GTK. By default, Liberica tries to use the accelerated EGL pipeline, which requires the presence of EGL libraries. If they are not found, the implementation falls back to software rendering.
Use the following command line options to specify the rendering pipeline:
-
-Dprism.order=sw forces the use of software rendering pipeline. *
-
-Dprism.order=es2 forces the use of EGL pipeline and hardware acceleration. *
-
-Djavafx.platform=gtk if you would like to launch a LibericaFX application using Liberica from X11.
-
Not supported on Raspberry Pi 4.
Please refer to the following wiki for more information.
Device IO API for the Raspberry Pi
Liberica JDK 16 comes with a bundled OpenJDK Device I/O (DIO) API implementation module. DIO provides a Java API for accessing Raspberry PI GPIO pins and for communicating with peripheral devices:
-
General Purpose Input/Output (GPIO).
-
Inter-Integrated Circuit Bus (I2C), Serial Peripheral Interface (SPI).
-
Universal Asynchronous Receiver/Transmitter (UART).
Please refer to the following wiki for more information.
Security Baselines
BellSoft Liberica follows the security baselines for Oracle Java SE. Please refer to the Oracle documentation for a list of issues fixed in a given release.
Known Issues
LibericaFX and EGL on Raspbian
As of 2017, the default location of Broadcom libEGL.so and libGLESv2.so has changed in Raspbian OS. If you’d like to leverage hardware EGL acceleration available from Broadcom video drivers in LibericaFX while running a recent Raspbian OS, run the following command:
cd /opt/vc/lib
sudo ln -s libbrcmEGL.so libEGL.so
sudo ln -s libbrcmGLESv2.so libGLESv2.soIssues fixed
