simple-java-mail: multi-release jar for jdk11+ missing

I am using the lib for a javafx application which I have ported from javafx8 to javafx11 and openjdk 11.

In order to use the lib I had to modularize the lib myself and therefore the question if it is possible to get a multi-release jar which can be used in java8 and java 9+ ?

Here is my config to use the lib (I have used moditec to modularize the lib):
