Run Eclipse on Java 17 (latest LTS JDK) [message #1844564]

Hello

Any possibility to run Eclipse on the latest LTS JDK?
Currently i see this exception:
index.php/fa/40992/0/

OS: macOS Big Sur
Java:
- java version "17" 2021-09-14 LTS
- Java(TM) SE Runtime Environment (build 17+35-LTS-2724)
- Java HotSpot(TM) 64-Bit Server VM (build 17+35-LTS-2724, mixed mode, sharing)

With Java 11 all works fine.

Can you share what you have for -vm in the eclipse.ini file? I have the following and it works fine.

-vm
/Users/jay/Java/jdk-17/Contents/Home/bin/java

I don't see this problem on the following configuration

OS: macos 11.6
Java: Java 17 hotspot
arch: x86_64
Eclipse committers package.

Can you please check whether you get java 17 as default with
/usr/libexec/java_home
and architecture matches with java and eclipse.
you can get architecture of JVM using
/usr/libexec/java_home -V

I have changed only:

Info.plist - configured right JDK (11 or 17)
index.php/fa/40994/0/

eclipse.ini - only increased memory parameters
index.php/fa/40995/0/

Java configuration:
index.php/fa/40996/0/

Maybe this is because JDK 17 architecture is arm64?
Currently i have latest macbook on m1 processor and installed it

But eclipse build is for x86_64 architecture

JDK 17 (arm64) works much faster on m1 cpu, as example i've got 65% reduced build time for one of our big projects which is ready to migrate to Java 17
Java 17 support installed in eclipse from Marketplace works fine with projects configured to use JDK 17 (arm64)

I think for now for me Eclipse still will be started with JDK 11 (x86_64) and I will migrate it to JDK 17 (arm64) when Eclipse release bundle for macOS (arm64) will be ready

Hi Alexandr,

The architecture types of Eclipse and the JVM should match. So, the combinations that will work on Mac M1 are:

Eclipse (x86_64) with Java (x86_64)
Eclipse (arm64) with Java (arm64)

These combinations will not work:

Eclipse (x86_64) with Java (arm64)
Eclipse (arm64) with Java (x86_64)

The Eclipse installer and IDE packages for Mac arm64 are not yet available, but the Eclipse SDK build for arm64 is available here [1]. You need the Mac OSX (64 bit version for Arm64/AArch64) download from the page and should be able to run this with Java 17 (arm64).

Please note that it's the base Eclipse SDK and you will have to install the additional plugins that are required.

Which specific plugins or components are you missing when using the installer DMG package eclipse-SDK-4.21-macosx-cocoa-aarch64.dmg from Lakshmi's URL above?

After installing the DMG you can add components in Menu Help -> Install New Software -> Add...

Components from other sources you can include there by pointing to a new installation site, for Eclipse MAT for example:
