Uncompress it: $ tar -xvf jdk-9.0.4_linux-圆4_bin.tar Download the 64-bit (or 32-bit) Linux “compressed binary file” into your home directory – it has a “.tar.gz” file extension. and this is working so far for me, in the limited testing I've done so far, with the vanilla 1.17 server JAR I downloaded from. jdk-16.0.1+9-jre/bin/java: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV),ĭynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, OpenJDK Server VM AdoptOpenJDK-16.0.1+9 (build 16.0.1+9, mixed mode) OpenJDK Runtime Environment AdoptOpenJDK-16.0.1+9 (build 16.0.1+9) Those choices have given me a working Java 16: $. See this question for more on JDK vs JRE. The Java Development Kit (JDK) includes more tools, but the JRE is a smaller download and installation, so I went for that. So the Java Runtime Environment (JRE) is fine. To run Minecraft, all we need is a java binary.The alternative option here is OpenJ9, but I believe that Mojang ship and test Minecraft with the HotSpot JVM, so that's what I chose.This Minecraft Paper server post about Java 16 explains more. Note this isn't a "Long Term Support" (LTS) version.Chose because Java 16 is the minimum for Minecraft 1.17 (see top of post).I went to and made the following choices: Luckily, AdoptOpenJDK (run by a community of Java User Group members, including some big names) seem to make a wider variety of Java binaries available for download. I think this may be supported by the processor on the Raspberry Pi 4, but not by the default OS. So, summary so far: Oracle supply a Java 16 JDK at, but the only ARM binary there is aarch64. (If I've misunderstood here, I'd appreciate if someone could correct me so I can learn.) If I read that right, although we could edit /boot/config.txt to include the arm_64bit=1, that would give us a 64 bit kernel, but not the ability to run 64 bit aarch64 binaries, because we still have a 32 bit userland. This article - "How to Make Your Raspberry Pi 4 Faster with a 64 Bit Kernel" helped me to understand a little more. I believe (I'm no expert) that the Raspberry Pi 4 CPU is able to run aarch64 code, but the current default OS doesn't support it. usr/lib/jvm/java-8-openjdk-armhf/jre/bin/java: ELF 32-bit LSB executable, ARM,ĮABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3,įor GNU/Linux 3.2.0, BuildID=6d2781f51a497603976e8fee28b888bd771fd5b7, stripped Version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1,Ĭompare this with the working Java 8 binary I have - note "32-bit" here: $ file /usr/lib/jvm/java-8-openjdk-armhf/jre/bin/java jdk-16.0.1/bin/java: ELF 64-bit LSB shared object, ARM aarch64, If we use file on that binary, we can see a bit more detail: $ file. jdk-16.0.1/bin/java: cannot execute binary file: Exec format error The Java 16 binary in the openjdk-16.0.1_linux-aarch64_ file I downloaded from gives an error when run on my Raspberry Pi 4: $. However, as of snapshot 21w19a, which was a few snapshots before the 1.17 release, Java 16 has become the minimum for Minecraft. I have been running a Minecraft server on a Raspberry Pi 4, using Java 8, installed via sudo apt install openjdk-8-jdk. I wrestled with the same issue a few days ago. * 1 /usr/lib/jvm/java-1.16.0-openjdk-armhf/bin/java 1131 manual modeĢ /usr/lib/jvm/java-1.8.0-openjdk-armhf/bin/java 1131 manual modeģ /usr/lib/jvm/java-8-openjdk-armhf/jre/bin/java 1081 manual mode Linux raspberrypi 5.10.17-v7l+ #1403 SMP Mon Feb 22 11:33: armv7l GNU/LinuxĪnd these are the options for sudo update-alternatives -config java: Selection Path Priority StatusĠ /usr/lib/jvm/java-1.16.0-openjdk-armhf/bin/java 1131 auto mode Here's a bit of system information in case it's useful: It appears this is the wrong version, but neither of the Linux downloads on the website worked, so I'm not sure what is wrong. When I try to run java -version, I get this error: bash: /usr/bin/java: cannot execute binary file: Exec format error I then followed these instructions to install it. There is no openjdk-16-jdk package so I downloaded the tar file for Linux / AArch64 as the Pi has an ARM processor. I'm running a minecraft server and there was an update recently which requires Java 16, but I have Java 8 installed. I am trying to install OpenJDK 16 on my Raspberry Pi 4.
