I suggest you contact the maintainer of this library to publish
a version that can be run as a module.  These libraries fail to be
loaded as automatic modules because they reference classes that are
not in the local module.

com.sun.jna.Native is in a different artifact net.java.dev.jna:jna:4.4.0.
When you place it in the module path as an automatic module, the main class
is expected to be local in the same module.  Since it’s in a different
module, it fails to load jna-platform-4.4.0.jar as automatic module.

jdeps -jdkinternals shows that it depends on an internal API. 

jna-platform-4.4.0.jar -> java.desktop
   com.sun.jna.platform.WindowUtils$MacWindowUtils$1  -> java.awt.peer.ComponentPeer                        JDK internal API (java.desktop)

Similarly, the other InvalidModuleDescriptorException you got indicates
that it fails to load the JAR file as automatic module and reconstitute
the module descriptor.

There exists META-INF/services/org.apache.batik.script.InterpreterFactory 
config file with a provider class that is not in this module.

Similar to batik-script case.
