Quarkus seems to need less memory on Java 15 and both Spring and Quarkus have a bit less loaded classes. I waited two minutes before taking each screenshot below.
#INSTALL OPENJDK 11 RASPBERRY PI INSTALL#
I installed this on my Ubuntu PC with sudo apt install visualvm and extended the startup commands on the Raspberry Pi so a connection can be made from another PC. Let’s go a step deeper and use VisualVM to inspect the application. No important differences here, the newer JDK doesn’t seem to have any influence here. $ java -jar java-spring-rest-db-0.0.1-SNAPSHOT.jar $ cd JavaOnRaspberryPi/Chapter_10_Spring/java-spring-rest-db/target/
To compare the startup speeds, I reused the Spring and Quarkus applications of the previous article. OpenJDK 64-Bit Server VM Zulu15.27+17-CA (build 15+36, mixed mode) You can install Java to Raspbian by running the following command. We are using the package default-jdk as this will always point to the latest available version of the JDK for Raspbian. OpenJDK Runtime Environment Zulu15.27+17-CA (build 15+36) In this guide, you will be installing OpenJDK 11 as it is the latest version of Java available for Raspbian Buster. Vendor | Use | Version | Dist | Status | IdentifierĪdoptOpenJDK | | 11.0.8.hs | adpt | | 11.0.8.hs-adpt With the SDKMAN tool, you can get a list of available JDKs on your Raspberry Pi and switch to Java 15 with a single command: sdk install java 15.0.0-zulu.
#INSTALL OPENJDK 11 RASPBERRY PI FREE#
Immediately after that, Azul released Azul Zulu OpenJDK 15, including a new version of their free Zulu Embedded JDK, including a version for ARM 64-bit, which is ideal for the latest Raspberry Pi boards! OpenJDK Java 15 was released on, check out the Java Version Almanac for more details. OpenJDK 64-Bit Server VM (build 11.0.8+10-post-Ubuntu-0ubuntu120.04, mixed mode) OpenJDK Runtime Environment (build 11.0.8+10-post-Ubuntu-0ubuntu120.04)
That version of Ubuntu comes with OpenJDK 11 pre-installed. Azul Zulu OpenJDK 15 on Raspberry Pi September 21, 2020įor this post I did some experiments with Java 15, reusing the Ubuntu 64bit SD card which was also used for my earlier post " Startup Speed of Spring and Quarkus JARs on the Raspberry Pi".
