Installing logstash 6.7 with OpenJDK-11

Hi there
Now that Oracle has decided to make the Java installation more troublesome I decided to try Openjdk instead. It says on the Elastic support matrix that both ElasticSearch and Logstash supports Openjdk-11.

However, when attempting to install logstash using stable main it crashes for me.

sudo apt-get install logstash

Poked around a bit on the forums and found something about JAVA_HOME not being set.

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64

Adding it to the path too and testing it:

export PATH=$PATH:$JAVA_HOME/bin
java --version
openjdk 11.0.3 2019-04-16
OpenJDK Runtime Environment (build 11.0.3+7-Ubuntu-1ubuntu1)
OpenJDK 64-Bit Server VM (build 11.0.3+7-Ubuntu-1ubuntu1, mixed mode, sharing)

But it still fails with the same error message.

Running on:

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 19.04
Release:        19.04
Codename:       disco

What am I missing? I can't be the only one running into this but yet I can find so little information about it.

Kind regards,

A search for that in the forum would find you this post.

Hi Badger
Thank you for your answer. I don't see any option to use Openjdk version 8 anywhere, neither in the Elastic compatibility matrix, nor even an option to install it in Ubuntu.

If you are referring to Oracle v8 I understand. But I rather avoid using that version given the recent development with the license and installation options.

Kind regards,

I guess you did refer to openjdk-8 after all. I looked at it and it's not available on Ubuntu 19.04:

Looking at the matrix though it should be compatible with openjdk-11:

Guess I am forced to use another version of Ubuntu.

Kind regards,

If anyone else finds a resolution to this I'd be grateful for any information.

Kind regards,
