Comment 30 for bug 1754886

Seeing your log, I noticed your java version was 11.0.3

You need to use java 8:

$ java -version
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

I suggest you to either uninstall your java 11 or use "sudo update-alternatives --config java" to switch your default java to version 8:

Afterwards, don't forget to rerun the workaround steps:

$ sudo wget http://archive.ubuntu.com/ubuntu/pool/universe/e/eclipse/libequinox-osgi-java_3.8.1-8_all.deb

$ sudo dpkg -x ./libequinox-osgi-java_3.8.1-8_all.deb /
$ sudo apt install --reinstall libequinox-osgi-java
$ eclipse #(this should launch)
