I was able to set default java-8 or java-11. Notes: the installation of Oracle Java 11 or 12 does not help either. icedtea-netx_1.6.2-3ubuntu1_bĪlso we need to pin/hold the versions of such packages with single long command below: cat <

#Java openjdk install#

So the commands to install are the following (we remove existing OpenJDK and then install deb-packages manually): sudo apt purge oracle-java11-* -y It is usually not recommended, but we do not have other methods with positive result.

Java-1.8.0-openjdk-amd64 1081 which javawsĪfter some trial and error I found only one useful solution - we need to install normal OpenJDK 8 from previous Ubuntu 16.04 LTS manually with commands below. Nevertheless, when I finished, it was not detected by firefox (maybe some command was missing).Īlso, find below the output of those commands (after trying installing according to your answer): update-java-alternatives -l I tried installing only openjdk-8, and then build icedtea from source. The ClassNotFoundException: sun/misc/JarIndex is what made me thought that is due to the dependency on jdk11, since this class seems to have been removed in Java 9. Java.io.FileNotFoundException: /home/roman/.config/icedtea-web/deployment.properties (No existe el archivo o el directorio) at java.base/java.io.FileInputStream.open0(Native Method) The application has not been initialized, for more information execute javaws/browser from the command line and send a bug report. : Fatal: Launch Error: Could not launch JNLP file. This is the output when I try to launch from firefox a jnlp application: Denying permission: ('' '') So, how can I achieve that icedtea-8 is installed with openjdk-8, and not 11? My guess is that I installed some PPA that now produces this situation where jdk-11 is a more up to date choice than any jdk-8 package. I suspect that jdk-11 does not include some libraries required for this. While it is expected to depend on openjdk-8, not 11 (according to ubuntu packages website). Icedtea-netx librhino-java libtagsoup-java openjdk-11-jre So I removed everything, started installation again, and found that apt-get install icedtea-8-plugin depends on: ca-certificates-java default-jre default-jre-headless icedtea-8-plugin After inspection, some libraries seem to be missing in Java. All the jnlp applications I tried give execution error.
