The full version string for this update release is 13.0.2+9. The version number is 13.0.2.
Liberica is a certified, Java SE 13.0.2-compliant distribution of OpenJDK 13.0.2 which works on embedded devices (Linux ARM64, Linux ARMv7, including Raspberry Pi 2 & 3 (ARMv6 hardfloat). It has the following notable additions:
- Linux x86_64 version contains experimental support for ZGC.
- Linux x86_64, ARMv8 and ARMv7 distributions include a choice of Client VM, Server VM and Minimal VM.
- Alpine Linux x86_64 version is build with musl support.
- Linux ARMv7 distribution contains Device IO API compiled for Raspberry Pi.
Please refer to the Oracle JDK 13.0.2 release notes for further information on JDK 13.0.2 features. This document further outlines the peculiarities of Liberica distribution as compared to Oracle JDK 11 distribution.
Liberica is tested and certified on Raspberry Pi 2 & 3 running the following OSes:
- Raspbian OS (armhf)
- OpenSUSE (armv8)
It is also known to work with Debian (armhf) and Ubuntu (armhf).
Liberica JDK 13.0.2 for Embedded are distributed as .rpm, .deb and .tar.gz packages. Please select the one which is most appropriate for your purposes.
Liberica 13.0.2 introduced all new features supported by OpenJDK https://www.oracle.com/technetwork/java/javase/13all-relnotes-5461743.html.
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.
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.
Liberica JDK 13.0.2 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.
Please refer to the following wiki for more information.
Liberica JDK 13.0.2 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.
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.
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.so
