## 9.3.0 [logstash-ki-9.3.0]

**Logstash will not start with bundled JDK on aarch64 downloaded artifacts**
**Logstash will not start with bundled JDK on aarch64 Linux/MacOs and x86_64 Windows**

Applies to: {{ls}} 9.3.0

::::{dropdown} Details

On `aarch64`, {{ls}} 9.3.0 fails to start when installed from .deb, .rpm, or .tar packages and using the bundled JDK.
This is due to an incorrect JDK version being included in those packages.

Using a JDK provided via `LS_JAVA_HOME` works as expected. Docker images and non-`aarch64` architectures are not affected.
All {{ls}} 9.3.0 artifacts were bundled with Linux x86_64 JDK due to a bug in artifact generation.
Starting {{ls}} on Windows or aarch64 Linux/MacOS with 9.3.0 artifacts results in an fatal error as the bundled JDK is not compatible with those platforms.

This issue affects:
* logstash-9.3.0-linux-aarch64.tar.gz
* logstash-9.3.0-darwin-aarch64.tar.gz
* logstash-9.3.0-windows-x86_64.zip
* logstash-9.3.0-arm64.deb
* logstash-9.3.0-aarch64.rpm
* logstash-oss-9.3.0-linux-aarch64.tar.gz
* logstash-oss-9.3.0-darwin-aarch64.tar.gz
* logstash-oss-9.3.0-windows-x86_64.zip
* logstash-oss-9.3.0-arm64.deb
* logstash-oss-9.3.0-aarch64.rpm

This issue does NOT affect:
* logstash-9.3.0-linux-x86_64.tar.gz
* logstash-9.3.0-x86_64.deb
* logstash-9.3.0-x86_64.rpm
* logstash-oss-9.3.0-linux-x86_64.tar.gz
* logstash-oss-9.3.0-x86_64.deb
* logstash-oss-9.3.0-x86_64.rpm
* Docker images

For this reason the download links to the affected artifacts have been removed from the [{{ls}} Download page](https://www.elastic.co/downloads/logstash) for version 9.3.0.

As a workaround, users can provide an external and compatible JDK via the `LS_JAVA_HOME` environment variable.
