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.

This error (and others like it) is raised when an old version of the Jalview Webstart JNLP is being used to launch the latest version of the application (for instance, because you have created your own JNLP file in order to increase the memory available to Jalview).
