--- Comment #3 from Fridrich Strba ---
OK, so I have taken some time and now I found the reason why this is not
working with our OpenJDK. Here is the background while I am trying to come with
a solution:
In JDK 11, Oracle removed several JavaEE modules from which also the
java.activation module that contains javax.activation package. Since Java 9
those modules were not directly visible without making them visible with
--add-modules command-line option.
The x-pack-watcher module of elastic search uses the javax.activation and also
distributes the activation-1.1.1.jar. The plugin-security.policy files gives to
the plugin and the dependent jars all permissions they need to operate.
Now, in openSUSE version of OpenJDK 11, we bring back some of the JavaEE
modules that a load of our packages use. The way we bring them back makes them
directly visible. That means, that if elasticsearch runs with our OpenJDK 11,
the javax.activation package is not resolved from the distributed jar, but from
the module included in the OpenJDK. But, this module does not have the same
security permission as the activation-1.1.1.jar included with elasticsearch.
Hence, elasticsearch exits with a security exception.
I am currently trying to look at a way to merge the modules without making them
visible by default. Without success for the while, but I am not giving up.
Eventually, there is a flag in our OpenJDK 11 build that disables the back
merging of those modules. But if we disable that, a load of our packages will
stop building.
